Pronunciation

Forms

calefaciō (present infinitive calefacere, perfect active calefēcī, supine calefactum); third (-iō variant) conjugation, suppletive[1] Also contracted calfaciō and calficiō, and Quintilian discusses the difference between calefaciō and calfaciō.[2] The passive is cal(e)fīō.[2][3]

Etymology

It is a compound of caleō “to be warm” and faciō “to make”.[2][1] De Vaan traces ⟨caleō⟩ to Proto-Italic *kalē-, a stative verb from Proto-Indo-European *ḱlh₁-eh₁- (“to be hot”).[4]

Earliest recorded meaning

The OLD's earliest citations are from Plautus, of heating.[2] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

It meant to make hot, heat, warm, as in Plautus, Lucretius and Cicero; of pungent substances, to produce a sensation of heat in the body, as in Celsus; and figuratively to stir to activity, rouse, as in Cicero's letters, calefac hominem “warm the man up”.[2]

In Ecclesiastical Latin it meant to warm.[6]
