Sambalpuri Odia is an Indo-Aryan language variety spoken in western Odisha, India. It is alternatively known as Western Odia, and as Kosali (with variants Kosli, Koshal and Koshali), a recently popularised but controversial term, which draws on an association with the historical region of Dakshina Kosala, whose territories also included the present-day Sambalpur region.
Its speakers usually perceive it as a separate language, while outsiders have seen it as a dialect of Odia, and standard Odia is used by Sambalpuri Odia speakers for formal communication. A 2006 survey of the varieties spoken in four villages found out that they share three-quarters of their basic vocabulary with Standard Odia.
