IPA: /ʌnˈtʃuːd/
KK: /ʌnˈtʃud/
Describing something that has not been bitten or ground down by teeth.
The dog left an unchewed piece of food on the floor.
Unchewed → It is formed from "un-" (meaning not) and "chewed" (from Old English "ceowan", meaning to chew). The word "unchewed" means not chewed or still in its original state before chewing.
Think of something that is 'not' ('un-') 'chewed' — that's why unchewed refers to food that hasn't been chewed yet.
