So I was working on my lexemes for #lexarch week 3, and while I will post the full list later, one word stuck out for...interesting reasons.
The word, Kukāk [kʷukʷɒk], which means "shield", derives from the words for "arm or forelimb", Kuluk [kʷuluk], and "shell/carapace", Kāg [kʷɒg], respectively.
