Kongu Tamil
Kongu Tamil (Tamil: கொங்குத் தமிழ்) is the dialect of Tamil language that is spoken in Kongu Nadu, which is the western region of Tamil Nadu. It is originally known as "Kangee"` or "Kongalam" or "Kongappechu".
Etymology
The name Kongu etymologically means 'border' in Sangam Tamil. Alternative theories seems to point at 'Ganga' as the source for the name. Gangeya (Kaangeyam) and Ganganadu are alternative historical names for the Kongu region.
Variations
The speciality of Kongu Tamil is the use of the alveolar ற - Tra/Dra (as in the English word track) instead of retroflex T/D (ட) of standard tamil. For example 'ennuDaya' (mine) of standard Tamil is pronounced enRa in the Kongu dialect. Additionally the use of guttural nasal (ங்) that sounds "ng" as in the English word Gang, is more prevalent in Kongu Tamil, leading to situations where the grammar of Kongu Tamil would not fit into the grammar of standard Tamil (as laid down in authoritative treatises like Tolkappiyam and Nannool). One of the examples is the use of ங் to end a word like வாங் "vaang", means 'come' expressed in a respectful tone, which in standard Tamil would be "vaanga".
