IPA: //ʌnˈtʃuːəbl//
KK: /ʌnˈtʃuːəbl/
Describing something, especially meat, that is difficult or impossible to chew due to its toughness or sinewy texture.
The steak was so tough that it was completely unchewable.
Unchewable → It is formed from "un-" (meaning not) and "chew" (from Old English "ceowan", meaning to bite or munch) and "-able" (meaning capable of). The word "unchewable" means not capable of being chewed or unable to be bitten or munched.
Think of 'not' ('un-') being added to 'chew' — that’s why unchewable means something that cannot be chewed.
