IPA: //ˈkrʊkˌnɛk//
KK: /ˈkrʊkˌnɛk/
A type of summer squash that has a long, curved neck and is usually yellow in color.
I bought a crookneck squash to make a delicious vegetable stew.
Crookneck is formed from "crook" (from Old English "crocca", meaning a bend or curve) and "neck" (from Old English "necca", meaning the part of the body connecting the head to the rest). The word describes a neck that is bent or curved, often used to refer to a type of squash with a distinctive shape.
Think of a 'bend' ('crook') in the 'neck' of a plant — that's why crookneck refers to a squash with a curved neck.
