Page number: 441
*karu°
• leg; foot.
Note: All eastern BT isolects: karu; all western BT isolects: kare. Also meaning ‘paw’ in several (if not all) dialect areas as well. The development of u > e in western Bungku-Tolaki is irregular, possibly the result of contamination from kae ‘hand’. [compare PMP *kaDus ‘scratch, rub’ (Dempwolff, in Zorc 1971 1681), PAN *karut ‘scrape, rasp’ (Blust 1989 256)]
