sermo

Etymology and origin of the Latin word sermo

Pronunciation

  • IPA (Classical): [ˈsɛr.moː][1]
  • IPA (Ecclesiastical): [ˈsɛr.mo][1]

Forms

sermō m (genitive sermōnis); third declension[1]

Etymology

It goes back to Proto-Italic *sermō and is usually derived from the root Proto-Indo-European *ser- (“to line up, link”) of serere “to join, string together”, as “a stringing together of words”.[2][1][3] De Vaan finds this not compelling but defensible, since words for “speech” in other languages have similar origins, and Varro already linked it with seriēs.[2][4] It cannot be connected with Oscan sverruneí because of the initial *sw-.[2]

Earliest recorded meaning

It is found from Plautus onwards,[2][5] in whom a character complains “your talk stinks to me”, and who has the proverb lupus in sermone “the wolf in the conversation”, for someone who turns up as he is being discussed.[6]

Semantic evolution

It meant one's words or talk, an informal address, and above all conversation or dialogue, which Cicero distinguishes from formal oratory (contentio).[6][4] It meant a discussion on a learned topic and a work written as a dialogue, and Horace called his Satires and Epistles sermones.[6] It also meant gossip and rumour, a topic of talk, a style of speaking, and a language or dialect, as in Cicero's Latinus sermo.[6][7]

In Christian Latin it meant the word of God and a homily or sermon, and in medieval Latin also a pledge, a command, and sermo regis, the king's protection.[8][9] Through French it gave English sermon around 1200.[3]
