Proto-Kui-Kuwi : *gaḍu
Meaning : much
Kuwi (Schulze) : gaddu "much, many"
Sunkarametta Kuwi : gaḍḍu
Notes : Burrow and Emeneau join this root with PK *kaṭ- 'sharp' (1135). Although in such languages as Telugu these two meanings are indeed connected ('sharp' - 'severe' - 'extreme', etc.), I think that these are two roots that have been contaminated in SDR. As for PK, such a comparison is impossible because of phonetical reasons.
