Kanikkaran language

Kanikkaran, also known as Kani, is a Dravidian language spoken by about 19,000 Kanikkar tribals in southern India. They dwell in forests and hills of Thiruvananthapuram and Kollam districts of Kerala, and Kanyakumari and Tirunelveli districts of Tamil Nadu. It is called malambhāsha, or "hill-language."

Vowels
Kanikkaran has 5 vowels, /a, e, i, o, u/. It demonstrates contrastive vowel length.

Consonants
They use the phoneme /l̩/ occasionally.

Kanikkaran has transformed words in Malayalam starting with /a/ into /e/. añcu (5) becomes eñcu, ari (rice) becomes ei, arivāḷu (sickle) becomes erivāḷu, aluku (split reed) becomes elakku. It also adds a suffix -in or -n after all noun stems, except for nouns ending with -n in accusative.

Grammar
The language cannot use personal terminations, similar to Old Malayalam. Example: pōvā (go or going or let's go) and vārā (will come, or "see you").
