Where it comes from
The adjective is derived from Late Middle English musty; further origin uncertain, possibly from one of the following: Compare Middle French moisi (“mouldy”), an adjective use of the past participle of moisir (“(to cause) to go mouldy, to moulder”) (modern French moisir), from Latin mūcēre, the present active infinitive of Old Latin mūceō (“to be mouldy or musty”): see above. The English word is analysable as must (“mould; mustiness”) + -y (suffix meaning ‘having the quality of’ forming adjectives); however, must is thought to be a back-formation from musty. The noun and verb are derived from the adjective.
