Konkani () is an Indo-Aryan language spoken by the Konkani people, primarily in the Konkan region, along the western coast of India. It is one of the 22 scheduled languages mentioned in the Indian Constitution, and the official language of the Indian state of Goa. It is also spoken in Karnataka, Maharashtra, Kerala, Gujarat as well as Daman, Diu and Silvassa.
Konkani is a member of the Southern Indo-Aryan language group. It retains elements of Vedic structures and shows similarities with both Western and Eastern Indo-Aryan languages. The first Konkani inscription is dated 1187 AD.
There are many Konkani dialects spoken along and beyond the Konkan region, from Daman in the north to Karwar in the south, most of which are only partially and mutually intelligible with one another due to a lack of linguistic contact and exchanges with the standard and principal forms of Konkani. It is also spoken by migrants outside of the Konkan proper; in Surat, Cochin, Mangalore, Ahmedabad, Karachi, New Delhi etc. Dialects such as Malvani, Chitpavani, East Indian, Koli and Aagri in coastal Maharashtra; are also threatened by language assimilation into the linguistic majority of non-Konkani states and territories of India.
Konkani belongs to the Indo-Aryan language branch. It is part of the Marathi-Konkani group of the southern Indo-Aryan languages. It is inflexive, and less distant from Sanskrit as compared to other modern Indo-Aryan languages. Linguists describe Konkani as a fusion of variety of Prakrits. This could be attributed to the confluence of immigrants that the Konkan coast has witnessed over the years.
It is quite possible that Old Konkani was just referred to as Prakrit by its speakers. Reference to the name Konkani is not found in literature prior to the 13th century. The first reference of the name Konkani is in "Abhanga 263" of the 13th century Hindu Marathi saint poet, Namadeva (1270–1350). Konkani has been known by a variety of names: Canarim, Concanim, Gomantaki, Bramana, and Goani. Learned Marathi speakers tend to call it Gomantaki.
