Pronunciation

  • IPA (Classical): [ˈfɫoːs][1]
  • IPA (Ecclesiastical): [ˈflɔs][1]

Forms

flōs m (genitive flōris); third declension[1]

Etymology

It is inherited from Proto-Italic *flōs (“flower”), inherited from Proto-Indo-European *bʰleh₃-ōs (“blossoming”).[2][1] Cognate with Oscan fluusaí (“to Flora”), Old Irish bláth (“flower”) and English bloom and English blossom.[2][3] The goddess Flōra was named from it, and her cult was known among the Oscans too.[2]

Earliest recorded meaning

De Vaan and Köbler date it from Livius Andronicus.[2][4] Plautus speaks of the bouquet of an old wine.[3] Köbler places Livius Andronicus before 200 BC.[4]

Semantic evolution

It meant a flower or blossom, and the flowering of a plant.[3] It also meant brightness, a scum or deposit on a surface, a fine powder, as in flōs salis, and the bouquet of wine.[3] Figuratively it was the best part or prime of something, flōs aetātis “the bloom of youth”, youthful beauty, and the flower or pick of a group, as in Ennius' flōs dēlībātus populī.[3][5]

In medieval Latin it meant fine flour, as already in Pliny, and the plural meant an anthology.[6] Old French flor gave English flower about 1200, and its spelling flour became the word for the finest part of meal.[7] flōreō gave English flourish, and flōridus gave English florid.[7] The DÉRom reconstructs Proto-Romance */ˈɸlor-e/, as in Italian fiore and French fleur.[8]
