Proto-Dravidian : *kac-
Meaning : angry, hostile
Notes : Unclear vowel length in PK. The root is highly unstable in many groups, probably due to contamination with *kas- 'bitter'. Especially dubious are the Kolami-Gadba forms, which may all be borrowings from South-Dravidian. Irregular *k- in PNDR, but since the root is expressive (reduplicated), the irregularity is not very significant.
