A genus–differentia definition is a type of intensional definition, it is composed of two parts: a genus: An existing definition that serves as a portion of the new definition. The differentia: The portion of the definition, not provided by the genus. For example, consider these two definitions: a triangle: A plane figure that has 3 straight bounding sides. A quadrilateral: A plane figure that has 4 straight bounding sides; those definitions can be expressed as one genus and two differentiae: one genus: the genus for both a triangle and a quadrilateral: "A plane figure" two differentiae: the differentia for a triangle: "that has 3 straight bounding sides." The differentia for a quadrilateral: "that has 4 straight bounding sides."The use of genus and differentia in constructing definitions goes back at least as far as Aristotle. The process of producing new definitions by extending existing definitions is known as differentiation; the reverse process, by which just part of an existing definition is used itself as a new definition, is called abstraction.

For instance, consider the following: a square: a quadrilateral that has interior angles which are all right angles, that has bounding sides which all have the same length. A part of that definition may be singled out: a square:, that has bounding sides which all have the same length.and with that part, an abstraction may be formed: a rectangle: a quadrilateral that has interior angles which are all right angles. The definition of a square may be recast with that abstraction as its genus: a square: a rectangle that has bounding sides which all have the same length; the definition of a square may be rearranged and another portion singled out: a square:, that has interior angles which are all right angles.leading to the following abstraction: a rhombus: a quadrilateral that has bounding sides which all have the same length. The definition of a square may be recast with that abstraction as its genus: a square: a rhombus that has interior angles which are all right angles. In fact, the definition of a square may be recast in terms of both of the abstractions, where one acts as the genus and the other acts as the differentia: a square: a rectangle, a rhombus.

A square: a rhombus, a rectangle. Hence, abstraction is crucial in simplifying definitions; when multiple definitions could serve well all such definitions apply simultaneously. Thus, a square is a member of both the genus rhombus. In such a case, it is notationally convenient to consolidate the definitions into one definition, expressed with multiple genera: a square: a rectangle and a rhombus.or equivalently: a square: a rhombus and a rectangle. More a collection of n > 1 equivalent definitions can be recast as one definition, expressed with n genera. Thus, the following: a Definition: a Genus1, a Genus2 and, a Genus3 and, a… and, a Genusn-1 and, a Genusn, which has some non-genus Differentia. A Definition: a Genus2, a Genus1 and, a Genus3 and, a… and, a Genusn-1 and, a Genusn, which has some non-genus Differentia. A Definition: a Genus3, a Genus1 and, a Genus2 and, a… and, a Genusn-1 and, a Genusn, which has some non-genus Differentia. … a Definition: a Genusn-1, a Genus1 and, a Genus2 and, a Genus3 and, a… and, a Genusn, which has some non-genus Differentia.

A Definition: a Genusn, a Genus1 and, a Genus2 and, a Genus3 and, a… and, a Genusn-1, which has some non-genus Differentia.could be recast as: a Definition: a Genus1 and a Genus2 and a Genus3 and a… and a Genusn-1 and a Genusn, which has some non-genus Differentia. A genus of a definition provides a means by which to specify an is-a relationship: A square is a rectangle, a quadrilateral, a plane figure, a… A square is a rhombus, a quadrilateral, a plane figure, a… A square is a quadrilateral, a plane figure, a… A square is a plane figure, a… A square is a…The non-genus portion of the differentia of a definition provides a means by which to specify a has-a relationship: A square has an interior angle, a right angle. A square has a straight bounding side. A square has a…When a system of definitions is constructed with genera and differentiae, the definitions can be thought of as nodes forming a hierarchy or—more generally—a directed acyclic graph; when a definition, S, is the tail of each of its successors S is called the species of each of its successors, each direct successor of S is called an individual of the species S.

Furthermore, the differentia of an individual

Keds was founded in 1916 and was acquired by Stride Rite Corporation; because the shoes had a soft rubber sole, they became known as sneakers as the rubber soles allowed "sneaking around silently". By the early 1920s, the shoes were worn by Olympic soccer players and international tennis champions, college athletes. In 1926, the Keds Triumph shoe was introduced.

Indiaglitz wrote "On the whole, the movie is good and takes one on a nostalgic journey". Behindwoods will be lapped up by the urban audience. If you thought Azhagi was a fantastic effort, chances are that you would have the same feeling with Tahnkar Bachaan’s new effort as well. Besides, the emotional aspect of the movie is sure to go down well with the female audience." The film grossed \$110 million at the box office. The movie is based on the novel Kalavupona Pozhudhugal by Thangar Bachchan himself. Producer Viswas Sundar has sent a two-hour international copy of the film with English and French sub-titles to Canada
