chicken 词源(Etymology) - 趣词词源[英文版]

chicken [chicken 词源字典]: chicken: [OE] Chicken is a widespread Germanic word (Dutch has kuiken, for instance, and Danish kylling), whose ancestor has been reconstructed as *kiukīnam. This was formed, with a diminutive suffix, on a base *keuk-, which some have claimed is a variant of a base which lies behind cock; if that is so, a chicken would amount etymologically to a ‘little cock’ (and historically the term has been applied to young fowl, although nowadays it tends to be the general word, regardless of age). Chick is a 14thcentury abbreviation.

The modern adjectival sense ‘scared’ is a 20th-century revival of a 17thand 18th-century noun sense ‘coward’, based no doubt on chicken-hearted.
