Pronunciation

  • Classical: [ˈmuː.ke.oː][1]
  • Ecclesiastical: [ˈmuː.t͡ʃe.o][1]

Forms

mūceō (present infinitive mūcēre); second conjugation, no passive, no perfect or supine stems[1]

Etymology

It is from Latin mūcus (“mucus, mould”) + -eō.[2][1] The TLL compares aceō (“to be sour”), which stands beside it in its only Classical passage.[3]

Earliest recorded meaning

Its only Classical record is in Cato (234–149 BC), De agri cultura, of wine that is neither sour nor musty.[2][4][3][5]

Semantic evolution

Lewis and Short mark it as pre-classical.[4] It lived on in spoken Latin: French moisir, Occitan mosir and dialectal Spanish musir continue it.[3][1]

Timeline

  • 234–149 BC – Cato uses it of musty wine.[2][3][5]
