Pronunciation

  • Classical: [mɔˈliː.nʊs][1]
  • Ecclesiastical: [moˈliː.nus][1]

Forms

molīnus (feminine molīna, neuter molīnum); first/second-declension adjective[1]

Etymology

It is from Latin mola (“millstone, mill”) + -īnus,[2][3] although Wiktionary forms it from molō (“to grind”) instead.[1]

Earliest recorded meaning

The first author to use it is Tertullian, who speaks of a millstone, molino saxo, tied to a person's neck.[3][4]

Semantic evolution

It is a rare word of Christian Latin,[2][1] meaning “belonging to a mill”.[5] Its feminine and neuter, molīna and molīnum, were used as nouns for the mill itself.[2] Medieval texts still use the adjective, of a donkey that works a mill and of a mill house.[6] Manuscripts often spell it mul-.[3]

The Romance words for “mill” go back to it: Sardinian molinu, Italian mulino, Spanish molino, Portuguese moinho and French moulin.[3]

Timeline

  • c. 160–220 AD – Tertullian writes of a millstone, molinum saxum.[3][2][4]
  • c. 1170–1190 – A cartulary speaks of a domus molina, a mill house.[6]

Meanings

Adjective

  1. (Late Latin, Ecclesiastical Latin) Of or belonging to a mill: saxum molīnum, a millstone.[2][3][5]
