Forms

calēscō (present infinitive calēscere); third conjugation, no passive, no perfect or supine stems[1]

Etymology

It is from caleō “to be warm” with the inchoative suffix -scō.[2][1][3] De Vaan traces ⟨caleō⟩ to Proto-Italic *kalē-, from Proto-Indo-European *ḱl̥h₁-éh₁- (“to be hot”).[4]

Earliest recorded meaning

The OLD's earliest citation is from Cato, of growing warm.[2] Köbler dates Cato 234–149 BC.[5]

Semantic evolution

It meant to grow warm or hot, to be heated, as in Cato and Lucretius, and Lewis & Short call it rare but classical.[2][6] Figuratively it meant to grow hot with love or desire, as in Terence and Ovid, and to be stirred, as in Ovid's est deus in nōbīs, agitante calēscimus illō “there is a god in us; when he stirs, we glow”.[2]

English borrowed it as the rare calesce.[1]
