cwd

If not borrowed from Latin cutis (“skin”), cwd is the sole surviving Celtic reflex (via Proto-Brythonic *kud, from Proto-Celtic *kutis) of Proto-Indo-European *kuH-ti-, which is composed of the root *kew(H)- (zero-grade without s-mobile form of *(s)kewH- (“to cover”)) +‎ *-tis (a deverbal abstract noun suffix). In addition to Latin cutis, cognate with Lithuanian kutỹs (“purse”), Old English hȳd (modern English hide (noun)).
