Origin & History of “must”

English has three words must. By far the commonest is of course the verb, ‘have to’ (OE), which originated in Old English as the past tense of the now obsolete mūt ‘may, must’. It has relatives in German muss and Dutch moet, but its ultimate origins are not known for certain (there may be some distant link with Germanic ‘measure’-words, such as English mete, suggesting a semantic progression from an original ‘time measured out for doing something’, through ‘have time to do something’, ‘be able to do something’, and ‘be allowed to do something’ to ‘have to do something’).

Must ‘unfermented grape juice for making into wine’ (OE) comes from Latin mustum ‘new wine’, a noun use of the adjective mustus ‘new’. Mustard is a derivative. And the esoteric must ‘sexual frenzy in elephants, camels, etc’ (19th c.) comes via Urdu from Persian mast ‘drunk’.
