Odia is the oldest-attested of the eastern Indo-Aryan languages in continuous literary use and was recognised as a classical language of India in 2014. Its script's rounded, umbrella-topped letterforms are a direct consequence of its writing material — a stylus drawing a straight horizontal line on a palm leaf splits the leaf along the fibre, so the curve is a structural solution, not an aesthetic one. The coastal register of this region, historically called Mughalbandi, is what became standard written Odia; the varieties around it were consequently reclassified as dialects of it, which is an artefact of where the printing presses stood.
Mughalbandi OdiaIndo-Aryan, Eastern
The Cuttack–Puri coastal register. The name comes from the tract's administrative history and stuck to the speech; nineteenth-century printing and schooling fixed it as the standard.

KatakiIndo-Aryan, Eastern
Cuttack city speech, carrying a layer of Persian and Urdu administrative and legal vocabulary from the centuries when the town was the region's revenue and court centre.
The Puri temple registerIndo-Aryan, Eastern
Not a dialect but a closed technical vocabulary — hundreds of terms for offerings, services, rights, utensils and calendar events used inside the temple and nowhere else, and a working knowledge of it is what separates a servitor from a visitor.
BaleswariIndo-Aryan, Eastern
The northern coastal speech, shading towards the Bengali of the Medinipur border.
GanjamiIndo-Aryan, Eastern
South of Chilika, with Telugu phonology and vocabulary increasingly present — the transition, not a break.
