A young cow or calf, or affectionately, the son or offspring of a cow.
Compound of 'cow' and '-son' (Old English 'sunu', meaning son or offspring). This rare or archaic term treats the calf as literally the 'son' of a cow, following patterns used for young animals.
Using '-son' for offspring appears in old animal terminology across English (like 'bull-calf' or 'cow-calf') and shows how pre-modern English speakers literally understood animals as family units with genealogy worth naming.
