Nature reserve
–
Nature reserves may be designated by government institutions in some countries, or by private landowners, such as charities and research institutions, regardless of nationality. Nature reserves fall into different IUCN categories depending on the level of protection afforded by local laws, early reservations often had a religious underpinning, such as the evil forest areas of West Africa which were forbidden to humans, who were threatened with spiritual attack if they went there. Sacred areas taboo from human entry to fishing and hunting are known by ancient cultures worldwide. The worlds first modern nature reserve was established in 1821 by the naturalist and explorer Charles Waterton around his estate in Walton Hall and he spent £9000 on the construction of a 3 mile long,9 ft tall wall to enclose his park from poachers. He tried to encourage birdlife by planting trees and hollowing out trunks for owls to nest in and he also invented artificial nest boxes to house starlings, jackdaws and sand martins and unsuccessfully attempted to introduce little owls from Italy. Drachenfels was protected as the first state-designated nature reserve in modern-day Germany, in Australia, a nature reserve is the title of a type of protected area used in the jurisdictions of the Australian Capital Territory, New South Wales, Tasmania and Western Australia. The term “nature reserve” is defined in the relevant statutes used in those states and territories rather than by a national statute. As of 2014,1767 out of a total of 10339 protected areas listed within the Australian National Reserve System used the term “nature reserve in their names, in Brazil, nature reserves are classified as ecological stations or biological reserves by the National System of Conservation Units. Their main objectives are preserving fauna and flora and other natural attributes, visits are allowed only with permission, and only for educational or scientific purposes. Changes to the ecosystems in both types of reserve are allowed to restore and preserve the balance, biological diversity. Ecological stations are allowed to change the environment within strictly defined limits for the purpose of scientific research. A wildlife reserve in Brazil is also protected, and hunting is not allowed, there are 30 nature reserves in Egypt which cover 12% of Egyptian land. Those nature reserves were built according to the laws no, 102/1983 and 4/1994 for protection of the Egyptian nature reserve. Egypt announced a plan from to build 40 nature reserves from 1997 to 2017, to protect the natural resources. The largest nature reserve in Egypt is Gebel Elba in the southeast, denmark has three national parks and several nature reserves, some of them inside the national park areas. The largest single reserve is Hanstholm Nature Reserve, which covers 40 km2 and is part of Thy National Park, in Sweden there are 29 national parks. The first of them were established in 1909, in fact, Sweden was the first European country that established 9 national parks. There are almost 4,000 nature reserves in Sweden and they comprise about 85% of the surface that is protected by the Swedish Enironmental Code

Water
–
Water is a transparent and nearly colorless chemical substance that is the main constituent of Earths streams, lakes, and oceans, and the fluids of most living organisms. Its chemical formula is H2O, meaning that its molecule contains one oxygen, Water strictly refers to the liquid state of that substance, that prevails at standard ambient temperature and pressure, but it often refers also to its solid state or its gaseous state. It also occurs in nature as snow, glaciers, ice packs and icebergs, clouds, fog, dew, aquifers, Water covers 71% of the Earths surface. It is vital for all forms of life. Only 2. 5% of this water is freshwater, and 98. 8% of that water is in ice and groundwater. Less than 0. 3% of all freshwater is in rivers, lakes, and the atmosphere, a greater quantity of water is found in the earths interior. Water on Earth moves continually through the cycle of evaporation and transpiration, condensation, precipitation. Evaporation and transpiration contribute to the precipitation over land, large amounts of water are also chemically combined or adsorbed in hydrated minerals. Safe drinking water is essential to humans and other even though it provides no calories or organic nutrients. There is a correlation between access to safe water and gross domestic product per capita. However, some observers have estimated that by 2025 more than half of the population will be facing water-based vulnerability. A report, issued in November 2009, suggests that by 2030, in developing regions of the world. Water plays an important role in the world economy, approximately 70% of the freshwater used by humans goes to agriculture. Fishing in salt and fresh water bodies is a source of food for many parts of the world. Much of long-distance trade of commodities and manufactured products is transported by boats through seas, rivers, lakes, large quantities of water, ice, and steam are used for cooling and heating, in industry and homes. Water is an excellent solvent for a variety of chemical substances, as such it is widely used in industrial processes. Water is also central to many sports and other forms of entertainment, such as swimming, pleasure boating, boat racing, surfing, sport fishing, Water is a liquid at the temperatures and pressures that are most adequate for life. Specifically, at atmospheric pressure of 1 bar, water is a liquid between the temperatures of 273.15 K and 373.15 K
3.
Drainage
–
Drainage is the natural or artificial removal of surface and sub-surface water from an area. The internal drainage of most agricultural soils is good enough to prevent severe waterlogging, all houses in the major cities of Harappa and Mohenjo-daro had access to water and drainage facilities. Waste water was directed to covered drains, which lined the major streets, the invention of hollow-pipe drainage is credited to Sir Hugh Dalrymple, who died in 1753. New drainage systems incorporate geotextile filters that retain and prevent fine grains of soil from passing into, geotextiles are synthetic textile fabrics specially manufactured for civil and environmental engineering applications. Geotextiles are designed to retain fine soil particles while allowing water to pass through, in a typical drainage system they would be laid along a trench which would then be filled with coarse granular material, gravel, sea shells, stone or rock. The geotextile is then folded over the top of the stone, groundwater seeps through the geotextile and flow within the stone to an outfell. In high groundwater conditions a perforated pipe is laid along the base of the drain to increases the volume of water transported in the drain. Alternatively, the prefabricated plastic drainage system made of HDPE called SmartDitch, often incorporating geotextile, over the past 30 years geotextile and PVC filters have become the most commonly used soil filter media. They are cheap to produce and easy to lay, with factory controlled properties that ensure long term filtration performance even in fine silty soil conditions, seattles Public Utilities created a pilot program called Street Edge Alternatives Project. The project focuses on designing a system to provide drainage that more closely mimics the natural landscape prior to development than traditional piped systems, the streets are characterized by ditches along the side of the roadway, with plantings designed throughout the area. An emphasis on non curbed sidewalks allows water to more freely into the areas of permeable surface on the side of the streets. Because of the plantings the run off water from the area does not all directly go into the ground. Sustainable Urban Drainage Systems are designed to encourage contractors to install drainage system that closely mimic the natural flow of water in nature. Since 2010 local and neighbourhood planning in the UK is required by law to factor SUDS into any development projects that they are responsible for, slot drainage has proved the most breakthrough product of the last twenty years as a drainage option. Both stainless steel and concrete channel slot drainage have become industry standards on construction projects, the civil engineer is responsible for drainage in construction projects. They set out from the all the roads, street gutters, drainage, culverts. During the construction process he/she will set out all the levels for each of the previously mentioned factors. Civil engineers and construction managers work alongside architects and supervisors, planners, quantity surveyors, typically, most jurisdictions have some body of drainage law to govern to what degree a landowner can alter the drainage from his parcel

Irrigation
–
Irrigation is the method in which a controlled amount of water is supplied to plants at regular intervals for agriculture. It is used to assist in the growing of crops, maintenance of landscapes. Additionally, irrigation also has a few uses in crop production. In contrast, agriculture that only on direct rainfall is referred to as rain-fed or dry land farming. Irrigation systems are used for dust suppression, disposal of sewage. Irrigation is often studied together with drainage, which is the natural or artificial removal of surface and sub-surface water from a given area, Irrigation has been a central feature of agriculture for over 5,000 years and is the product of many cultures. Historically, it was the basis for economies and societies across the globe, archaeological investigation has found evidence of irrigation where the natural rainfall was insufficient to support crops for rainfed agriculture. Ancient Egyptians practiced Basin irrigation using the flooding of the Nile to inundate land plots which had surrounded by dykes. The flood water was held until the sediment had settled before the surplus was returned to the watercourse. The Ancient Nubians developed a form of irrigation by using a device called a sakia. Irrigation began in Nubia some time between the third and second millennium BCE and it largely depended upon the flood waters that would flow through the Nile River and other rivers in what is now the Sudan. In sub-Saharan Africa irrigation reached the Niger River region cultures and civilizations by the first or second millennium BCE and was based on wet season flooding, terrace irrigation is evidenced in pre-Columbian America, early Syria, India, and China. These canals are the earliest record of irrigation in the New World, traces of a canal possibly dating from the 5th millennium BCE were found under the 4th millennium canal. Large scale agriculture was practiced and a network of canals was used for the purpose of irrigation. Ancient Persia as far back as the 6th millennium BCE, where barley was grown in areas where the rainfall was insufficient to support such a crop. The Qanats, developed in ancient Persia in about 800 BCE, are among the oldest known irrigation methods still in use today and they are now found in Asia, the Middle East and North Africa. The system comprises a network of wells and gently sloping tunnels driven into the sides of cliffs. The noria, a wheel with clay pots around the rim powered by the flow of the stream, was first brought into use at about this time

Arable land
–
Arable land is, according to one definition, land capable of being ploughed and used to grow crops. In Britain, it was contrasted with pasturable lands such as heaths which could be used for sheep-rearing. A quite different kind of definition is used by various agencies concerned with agriculture, the abandoned land resulting from shifting cultivation is not included in this category. Data for ‘Arable land’ are not meant to indicate the amount of land that is potentially cultivable, a briefer definition appearing in the Eurostat glossary similarly refers to actual, rather than potential use, land worked regularly, generally under a system of crop rotation. According to Food and Agriculture Organization of the United Nations the worlds Arable land amounted to 1,407 M ha, out of a total 4,924 M ha land used for agriculture, as for year 2013. Agricultural land that is not arable according to the FAO definition above includes, Permanent crop - land that produces crops from woody vegetation, other non-arable land includes land unsuitable for any agricultural use. Although such limitations may preclude cultivation, and some will in some cases preclude any agricultural use, for example, US NRCS statistics indicate that about 59 percent of US non-federal pasture and unforested rangeland is unsuitable for cultivation, yet such land has value for grazing of livestock. Similar examples can be found in many rangeland areas elsewhere, land incapable of being cultivated for production of crops can sometimes be converted to arable land. New arable land makes more food, and can reduce starvation and this outcome also makes a country more self-sufficient and politically independent, because food importation is reduced. This process is extremely expensive. An alternative is the Seawater Greenhouse which desalinates water through evaporation and condensation using solar energy as the energy input. This technology is optimized to grow crops on land close to the sea. The people covered the islands with a layer of seaweed. Israel, The construction of desalination plants along Israels coast allowed agriculture in areas that were formerly desert. The desalination plants, which remove the salt from water, have created a new source of water for farming, drinking. Slash and burn agriculture uses nutrients in wood ash, but these expire within a few years, terra preta, fertile tropical soils created by adding charcoal. Some examples of fertile land being turned into infertile land are. Rainforest deforestation, The fertile tropical forests are converted into infertile desert land, for example, Madagascars central highland plateau has become virtually totally barren, as a result of slash-and-burn deforestation, an element of shifting cultivation practiced by many natives

The Fens
–
The Fens, also known as the Fenland, is a naturally marshy region in eastern England. Most of the fens were drained several centuries ago, resulting in a flat, dry and it is one of the driest areas in England, thanks to a system of drainage channels and man-made rivers and automated pumping stations. A common misconception is that the fens are damp, in whole it occupies an area of nearly 1,500 sq mi. Most of the Fenland lies within a few metres of sea level, with the support of this drainage system, the Fenland has become a major arable agricultural region in Britain for grains and vegetables. The Fens are particularly fertile, containing half of the grade 1 agricultural land in England. The Fens have been referred to as the Holy Land of the English because of the monasteries, now churches and cathedrals, of Crowland, Ely, Peterborough. Other significant settlements in the Fens include Boston, Cambridge, Spalding, the Fens are very low-lying compared with the chalk and limestone uplands that surround them – in most places no more than 10 m above sea level. Indeed, as a result of drainage and the subsequent shrinkage of the peat fens, within the Fens there are a few hills, which have historically been called islands as they remained dry when the low-lying fens around them were flooded. The largest of the fen-islands is the Isle of Ely, on which the city of Ely was built. Some areas of the Fens were once permanently flooded, creating small lakes or meres, the rest of the Fenland was dedicated to pastoral farming, fishing, fowling and the harvesting of reeds or sedge for thatch. In this way, the medieval and early modern Fens stood in contrast to the rest of southern England, drainage in the Fenland consists of both river drainage and internal drainage of the land between the rivers. The internal drainage was organised by levels or districts, each of which includes the fen parts of one or several parishes, in the 17th century, the Great Level was divided into the North, Middle and South Levels for the purposes of administration and maintenance. In the 20th century, these levels have gained new boundaries, the South Level lies to the southeast of the Ouse Washes and surrounds Ely, as it did in the 17th century. The Middle Level currently lies between the Ouse Washes and the Nene, but historically lay between the Ouse Washes and Mortons Leam, a 15th-century canal which runs north of the town of Whittlesey. Deeping Fen, in the part of Lincolnshire, lies between the River Welland and the River Glen with its tributary the Bourne Eau. The Black Sluice District, much of which was known as the Lindsey Level when it was first drained in 1639, extends from the Glen and its water is carried through to the Haven at Boston. The above were all redrained at one time or another after the Civil War, at the end of the most recent glacial period, known in Britain as the Devensian, ten thousand years ago, Britain and continental Europe were joined by the ridge between Friesland and Norfolk. The topography of the bed of the North Sea indicates that the rivers of the part of eastern England flowed into the Rhine

England
–
England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west, the Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east, the country covers five-eighths of the island of Great Britain in its centre and south, and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight. England became a state in the 10th century, and since the Age of Discovery. The Industrial Revolution began in 18th-century England, transforming its society into the worlds first industrialised nation, Englands terrain mostly comprises low hills and plains, especially in central and southern England. However, there are uplands in the north and in the southwest, the capital is London, which is the largest metropolitan area in both the United Kingdom and the European Union. In 1801, Great Britain was united with the Kingdom of Ireland through another Act of Union to become the United Kingdom of Great Britain and Ireland. In 1922 the Irish Free State seceded from the United Kingdom, leading to the latter being renamed the United Kingdom of Great Britain, the name England is derived from the Old English name Englaland, which means land of the Angles. The Angles were one of the Germanic tribes that settled in Great Britain during the Early Middle Ages, the Angles came from the Angeln peninsula in the Bay of Kiel area of the Baltic Sea. The earliest recorded use of the term, as Engla londe, is in the ninth century translation into Old English of Bedes Ecclesiastical History of the English People. According to the Oxford English Dictionary, its spelling was first used in 1538. The earliest attested reference to the Angles occurs in the 1st-century work by Tacitus, Germania, the etymology of the tribal name itself is disputed by scholars, it has been suggested that it derives from the shape of the Angeln peninsula, an angular shape. An alternative name for England is Albion, the name Albion originally referred to the entire island of Great Britain. The nominally earliest record of the name appears in the Aristotelian Corpus, specifically the 4th century BC De Mundo, in it are two very large islands called Britannia, these are Albion and Ierne. But modern scholarly consensus ascribes De Mundo not to Aristotle but to Pseudo-Aristotle, the word Albion or insula Albionum has two possible origins. Albion is now applied to England in a poetic capacity. Another romantic name for England is Loegria, related to the Welsh word for England, Lloegr, the earliest known evidence of human presence in the area now known as England was that of Homo antecessor, dating to approximately 780,000 years ago. The oldest proto-human bones discovered in England date from 500,000 years ago, Modern humans are known to have inhabited the area during the Upper Paleolithic period, though permanent settlements were only established within the last 6,000 years

Netherlands
–
The Netherlands, also informally known as Holland is the main constituent country of the Kingdom of the Netherlands. It is a densely populated country located in Western Europe with three territories in the Caribbean. The European part of the Netherlands borders Germany to the east, Belgium to the south, and the North Sea to the northwest, sharing borders with Belgium, the United Kingdom. The three largest cities in the Netherlands are Amsterdam, Rotterdam and The Hague, Amsterdam is the countrys capital, while The Hague holds the Dutch seat of parliament and government. The port of Rotterdam is the worlds largest port outside East-Asia, the name Holland is used informally to refer to the whole of the country of the Netherlands. Netherlands literally means lower countries, influenced by its low land and flat geography, most of the areas below sea level are artificial. Since the late 16th century, large areas have been reclaimed from the sea and lakes, with a population density of 412 people per km2 –507 if water is excluded – the Netherlands is classified as a very densely populated country. Only Bangladesh, South Korea, and Taiwan have both a population and higher population density. Nevertheless, the Netherlands is the worlds second-largest exporter of food and agricultural products and this is partly due to the fertility of the soil and the mild climate. In 2001, it became the worlds first country to legalise same-sex marriage, the Netherlands is a founding member of the EU, Eurozone, G-10, NATO, OECD and WTO, as well as being a part of the Schengen Area and the trilateral Benelux Union. The first four are situated in The Hague, as is the EUs criminal intelligence agency Europol and this has led to the city being dubbed the worlds legal capital. The country also ranks second highest in the worlds 2016 Press Freedom Index, the Netherlands has a market-based mixed economy, ranking 17th of 177 countries according to the Index of Economic Freedom. It had the thirteenth-highest per capita income in the world in 2013 according to the International Monetary Fund, in 2013, the United Nations World Happiness Report ranked the Netherlands as the seventh-happiest country in the world, reflecting its high quality of life. The Netherlands also ranks joint second highest in the Inequality-adjusted Human Development Index, the region called Low Countries and the country of the Netherlands have the same toponymy. Place names with Neder, Nieder, Nether and Nedre and Bas or Inferior are in use in all over Europe. They are sometimes used in a relation to a higher ground that consecutively is indicated as Upper, Boven, Oben. In the case of the Low Countries / the Netherlands the geographical location of the region has been more or less downstream. The geographical location of the region, however, changed over time tremendously

Driving
–
Driving is the controlled operation and movement of a motorized vehicle with wheels, such as a car, motorcycle, truck, or bus by either a human or computer controller. The origin of the driver, as recorded from the 15th century, refers to the occupation of driving working animals. The verb to drive in origin means to force to move and it is first recorded of electric railway drivers in 1889 and of a motor-car driver in 1896. Early alternatives were motorneer, motor-man, motor-driver or motorist, french favors conducteur, while German influenced areas adopted Fahrer, and the verbs führen, lenken, steuern —all with a meaning steer, guide, navigate— translating to conduire. Her official reason was that she wanted to visit her mother, but unofficially she intended to generate publicity for her husbands invention, the automobile took off greatly afterwards and the Benzs family business eventually evolved into the present day Mercedes-Benz company. The 7. 6-mile journey took two hours, the descent was accomplished by putting the engine in low gear and doing lots of braking. In certain countries, especially the Scandinavian countries, driving and its equivalent word in the language has become a colloquialism for action in a general sense. For instance, the phrase Lets drive means roughly the same thing as the more common Lets go, Driving in traffic is more than just knowing how to operate the mechanisms which control the vehicle, it requires knowing how to apply the rules of the road. An effective driver also has an understanding of the basics of vehicle handling. Although direct operation of a bicycle and an animal are commonly referred to as riding. Driving over a distance is referred to as a road trip. A driver must have physical skills to be able to control direction, acceleration, another survey indicated that music could adversely affect a drivers concentration. Seizure disorders and Alzheimers disease are among the leading causes of mental impairment among drivers in the United States. Whether or not physicians should be allowed, or even required, to such conditions to state authorities. Driveability of a means the smooth delivery of power, as demanded by the driver. Typical causes of driveability degradation are rough idling, misfiring, surging, hesitation, a driver is subject to the laws of the jurisdiction in which he or she is driving. Most countries also have differing laws against driving while under the influence of alcohol or other drugs, aggressive driving and road rage have become problems for drivers in some areas. Some countries require a vision screening test for individuals to acquire or renew a drivers license, a 2010 systematic review found insufficient evidence to assess the effects of vision screening tests on subsequent motor vehicle crash reduction

Cycling
–
Cycling, also called bicycling or biking, is the use of bicycles for transport, recreation, exercise or sport. Persons engaged in cycling are referred to as cyclists, bikers, or less commonly, apart from two-wheeled bicycles, cycling also includes the riding of unicycles, tricycles, quadracycles, recumbent and similar human-powered vehicles. Bicycles were introduced in the 19th century and now approximately one billion worldwide. They are the means of transportation in many parts of the world. Cycling is widely regarded as an effective and efficient mode of transportation optimal for short to moderate distances. Cycling also offers a reduced consumption of fuels, less air or noise pollution. These lead to financial cost to the user as well as to society at large. By fitting bicycle racks on the front of buses, transit agencies can significantly increase the areas they can serve, in many countries, the most commonly used vehicle for road transport is a utility bicycle. These have frames with relaxed geometry, protecting the rider from shocks of the road, utility bicycles tend to be equipped with accessories such as mudguards, pannier racks and lights, which extends their usefulness on a daily basis. As the bicycle is so effective as a means of various companies have developed methods of carrying anything from the weekly shop to children on bicycles. Certain countries rely heavily on bicycles and their culture has developed around the bicycle as a form of transport. In Europe, Denmark and the Netherlands have the most bicycles per capita, road bikes tend to have a more upright shape and a shorter wheelbase, which make the bike more mobile but harder to ride slowly. The design, coupled with low or dropped handlebars, requires the rider to bend forward more, making use of stronger muscles, the price of a new bicycle can range from US$50 to more than US$20,000, depending on quality, type and weight. However, UCI regulations stipulate a legal race bike cannot weigh less than 6.8 kg, being measured for a bike and taking it for a test ride are recommended before buying. The drivetrain components of the bike should also be considered, a middle grade dérailleur is sufficient for a beginner, although many utility bikes are equipped with hub gears. If the rider plans a significant amount of hillclimbing a triple-chainrings crankset gear system may be preferred, otherwise, the relatively lighter and less expensive double chainring may be better. Much simpler fixed wheel bikes are also available, many road bikes, along with mountain bikes, include clipless pedals to which special shoes attach, via a cleat, enabling the rider to pull on the pedals as well as push. For basic maintenance and repairs cyclists can carry a pump, a repair kit, a spare inner tube, and tire levers
11.
Weather
–
Weather is the state of the atmosphere, to the degree that it is hot or cold, wet or dry, calm or stormy, clear or cloudy. Most weather phenomena occur in the lowest level of the atmosphere, Weather refers to day-to-day temperature and precipitation activity, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time. When used without qualification, weather is understood to mean the weather of Earth. Weather is driven by air pressure, temperature and moisture differences between one place and another and these differences can occur due to the suns angle at any particular spot, which varies with latitude. The strong temperature contrast between polar and tropical air gives rise to the largest scale atmospheric circulations, the Hadley Cell, the Ferrel Cell, the Polar Cell, Weather systems in the mid-latitudes, such as extratropical cyclones, are caused by instabilities of the jet stream flow. Because the Earths axis is tilted relative to its orbital plane, on Earths surface, temperatures usually range ±40 °C annually. Over thousands of years, changes in Earths orbit can affect the amount and distribution of energy received by the Earth, thus influencing long-term climate. Surface temperature differences in turn cause pressure differences, higher altitudes are cooler than lower altitudes as most atmospheric heating is due to contact with the Earths surface while radiative losses to space are mostly constant. Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location. The Earths weather system is a system, as a result. Human attempts to control the weather have occurred throughout history, and there is evidence that human activities such as agriculture, studying how the weather works on other planets has been helpful in understanding how weather works on Earth. A famous landmark in the Solar System, Jupiters Great Red Spot, is a storm known to have existed for at least 300 years. However, weather is not limited to planetary bodies, a stars corona is constantly being lost to space, creating what is essentially a very thin atmosphere throughout the Solar System. The movement of mass ejected from the Sun is known as the solar wind, on Earth, the common weather phenomena include wind, cloud, rain, snow, fog and dust storms. Less common events include natural disasters such as tornadoes, hurricanes, typhoons, almost all familiar weather phenomena occur in the troposphere. Weather does occur in the stratosphere and can affect weather lower down in the troposphere, Weather occurs primarily due to air pressure, temperature and moisture differences between one place to another. These differences can occur due to the sun angle at any particular spot, in other words, the farther from the tropics one lies, the lower the sun angle is, which causes those locations to be cooler due the spread of the sunlight over a greater surface. The strong temperature contrast between polar and tropical air gives rise to the large scale atmospheric circulation cells and the jet stream, Weather systems in the mid-latitudes, such as extratropical cyclones, are caused by instabilities of the jet stream flow

Old English
–
Old English or Anglo-Saxon is the earliest historical form of the English language, spoken in England and southern and eastern Scotland in the early Middle Ages. It was brought to Great Britain by Anglo-Saxon settlers probably in the mid 5th century, Old English developed from a set of Anglo-Frisian or North Sea Germanic dialects originally spoken by Germanic tribes traditionally known as the Angles, Saxons, and Jutes. As the Anglo-Saxons became dominant in England, their language replaced the languages of Roman Britain, Common Brittonic, a Celtic language, Old English had four main dialects, associated with particular Anglo-Saxon kingdoms, Mercian, Northumbrian, Kentish and West Saxon. It was West Saxon that formed the basis for the standard of the later Old English period, although the dominant forms of Middle. The speech of eastern and northern parts of England was subject to strong Old Norse influence due to Scandinavian rule, Old English is one of the West Germanic languages, and its closest relatives are Old Frisian and Old Saxon. Like other old Germanic languages, it is different from Modern English. Old English grammar is similar to that of modern German, nouns, adjectives, pronouns, and verbs have many inflectional endings and forms. The oldest Old English inscriptions were using a runic system. Old English was not static, and its usage covered a period of 700 years, from the Anglo-Saxon settlement of Britain in the 5th century to the late 11th century, some time after the Norman invasion. While indicating that the establishment of dates is a process, Albert Baugh dates Old English from 450 to 1150, a period of full inflections. Perhaps around 85 per cent of Old English words are no longer in use, Old English is a West Germanic language, developing out of Ingvaeonic dialects from the 5th century. It came to be spoken over most of the territory of the Anglo-Saxon kingdoms which became the Kingdom of England and this included most of present-day England, as well as part of what is now southeastern Scotland, which for several centuries belonged to the Anglo-Saxon kingdom of Northumbria. Other parts of the island – Wales and most of Scotland – continued to use Celtic languages, Norse was also widely spoken in the parts of England which fell under Danish law. Anglo-Saxon literacy developed after Christianisation in the late 7th century, the oldest surviving text of Old English literature is Cædmons Hymn, composed between 658 and 680. There is a corpus of runic inscriptions from the 5th to 7th centuries. The Old English Latin alphabet was introduced around the 9th century, with the unification of the Anglo-Saxon kingdoms by Alfred the Great in the later 9th century, the language of government and literature became standardised around the West Saxon dialect. In Old English, typical of the development of literature, poetry arose before prose, a later literary standard, dating from the later 10th century, arose under the influence of Bishop Æthelwold of Winchester, and was followed by such writers as the prolific Ælfric of Eynsham. This form of the language is known as the Winchester standard and it is considered to represent the classical form of Old English
