'juglike' originates from English, specifically the word 'jug' + the suffix '-like', where 'jug' meant 'a container for liquids' and '-like' meant 'similar to' or 'having the quality of'.

'jug' is recorded in Middle English as 'jugge' (or similar forms) and developed into the modern English 'jug'; the adjective-forming suffix '-like' comes from Old English '-lic' meaning 'having the body or form of', producing the compound 'juglike'.

Initially it meant 'similar in form to a jug', and this basic sense has remained stable into modern usage as 'resembling a jug'.
