Forms
mucegai n (plural mucegaiuri)[1] A variant is mucigai.[2][3] A regional form muștegai occurs in a charm: „Și te du-n codri pustii … În muștegai Și-n putregai” “and go to the empty forests… into mould and into rot”.[4][3]
Etymology
It is from Romanian muced (“mouldy, musty”), formed like putregai from putred.[5][4][2][3] Tiktin explains the ⟨g⟩ for ⟨d⟩ by ucide beside ucigaș.[5] Ciorănescu derives it from the verb mucezi in the same way.[6] Pascu saw the adjective with the suffix -aie.[6] Pușcariu and Wiktionary take it instead from a derivative Vulgar Latin *muccicālium, which also gave Italian moccicaglia.[6][1][7] The adjective continues Latin mūcidus (“mouldy”).[6]
Earliest recorded meaning
Tiktin's first record is of 1852.[5] MDA2 quotes Filimon from a 1957 edition of his works, in the figurative sense of decay.[3][4]
Semantic evolution
The word names the mould that grows on damp organic matter, and by extension damp in walls.[3][2] Figuratively it is decay or something repugnant, and an insult for old people: Creangă's mucegaiul de babă “that mouldy old hag”.[5][4] A prinde mucegai is used of people who grow old and dull.[4][8] Regionally it also means rust of cereals.[3]
