The Odia script is a Brahmic script used to write primarily Odia language and others including Sanskrit and other regional languages. It is one of the official scripts of the Indian Republic. The script has developed over more than 1000 years from a variant of Siddhaṃ script which was used in Eastern India, where the characteristic top line transformed into a distinct round umbrella shape due to the influence of palm leaf manuscripts and also being influenced by the neighbouring scripts from the Western and Southern regions.

An abugida – sometimes also called alphasyllabary, neosyllabary, or pseudo-alphabet – is a segmental writing system in which consonant–vowel sequences are written as units; each unit is based on a consonant letter, and vowel notation is secondary, similar to a diacritical mark. This contrasts with a full alphabet, in which vowels have status equal to consonants, and with an abjad, in which vowel marking is absent, partial, or optional – in less formal contexts, all three types of the script may be termed "alphabets". The terms also contrast them with a syllabary, in which a single symbol denotes the combination of one consonant and one vowel.
