Forms

mustos m or n (feminine singular mustoasă, masculine plural mustoși, feminine/neuter plural mustoase)[1]

Etymology

It is formed from Romanian must (“must, grape juice”) + -os.[2][3][4][5][6] The noun is from Latin mustum.[7]

The REW instead derives the adjective directly from Vulgar Latin *mustōsus, and Ciorănescu reports that view.[8][7] Candrea and Densusianu also start from the Latin adjective, and Wiktionary gives both explanations.[9][1] The Latin form is supported by Aromanian mustos “juicy”, which Papahagi derives from it, and by Italian mostoso, Spanish mostoso and Occitan mostos.[10][9][8]

Earliest recorded meaning

Tiktin's first record is of 1703, with the sense “juicy”.[5] MDA2 takes its first record from Budai-Deleanu's lexicon (1818).[3]

Semantic evolution

The adjective describes fruit full of juice, then trees full of sap and wood full of water.[3][4] Applied to soil it means rich and fertile, and figuratively plentiful: a calendar of 1844 has the saying „Rusalii ploioase, culesuri mustoase” “a rainy Whitsun, juicy harvests”.[4] In modern prose it describes savoury language, expressions full of meaning.[3][11]
