Pronunciation

  • Classical: [ˈfoː.mɛs][1]
  • Ecclesiastical: [ˈfɔː.mes][1]

Forms

fōmes m (genitive fōmitis); third declension[1]

Etymology

It is from Latin foveō (“to keep warm”).[2][3][4] De Vaan lists it among the derivatives of that verb, which goes back to Proto-Italic *foχweje/o- and Proto-Indo-European *dʰogʷʰ-éye- (“to burn”).[4] Following Schrijver, he takes the long ⟨ō⟩ of such derivatives to come from an unsyncopated ⟨*fowe-⟩, and notes that apart from fōculum they appear rather late.[4]

Earliest recorded meaning

It is found from Virgil on,[4] who tells how Achates struck a spark from flint and caught the flame in tinder (rapuitque in fomite flammam).[3][5]

Semantic evolution

In Classical Latin it meant chips of wood, tinder and other fuel for kindling or feeding a fire,[2][3] as in Lucan and Pliny the Elder.[3][5] Later writers used it figuratively for whatever feeds or stirs something: Gellius calls wine a fomes of the mind and of courage,[3] Prudentius speaks of the fomes peccati, the tinder of sin,[3][6] and the Vulgate of the tinder of envy.[3] Prudentius also uses it for warmth.[6] Medieval Latin kept these uses: fuel for a fire or a lamp, heat, food and incentive,[7] and in Britain it glossed Old English words for tinder.[8] In New Latin medicine it named a fomite, an object that carries infection.[1]
