Forms

fax f (genitive facis); third declension[1]

Etymology

It is inherited from Proto-Italic *fwak(w)-(ē-), of uncertain origin.[2][3][1] De Vaan considers a PIE *ǵʰwok-, with /o/ unrounded to /a/, which would make it cognate with Lithuanian žvãkė (“candle”); a link with Greek φώψ “light”, a Hesychian word, is uncertain.[2][1] He also derives facētus “clever” from the same stem, from “enlightened” to “clever”.[2] Wiktionary compares Etruscan face (“torch (?)”).[1]

Earliest recorded meaning

Plautus uses it.[2] Köbler dates Plautus c. 250–184 BC.[4]

Semantic evolution

In Classical Latin it was a torch for light, as Horace's man who walks with torches before nightfall, and a torch in processions, above all at weddings, so that by metonymy it meant marriage.[3] In poetry it was the light of the sun and stars, and it was a meteor or comet.[3][1] Figuratively it was what kindles passion or ruin, an incitement.[1][5] Döderlein calls it the general word for a torch, against taeda of pine and fūnāle of wax.[6]

In medieval Latin it kept the sense of a torch, of a heavenly light, and figurative uses.[7] It was borrowed as Italian face.[1]
