Forms

torpor m (genitive torpōris); third declension[1]

Etymology

It is from Latin torpeō (“to be numb, sluggish”) + -or.[2][1] De Vaan traces ⟨torpeō⟩ to Proto-Italic *torp-ē- (“to be stiff”), Proto-Indo-European *tr̥p-éh₁- (“to be stiff”), cognate with Lithuanian tirpti (“to grow stiff”).[3]

Earliest recorded meaning

The OLD's earliest citation is Lucilius, of heaviness, drowsiness.[2] Köbler dates Lucilius c. 180–102 BC.[4]

Semantic evolution

It meant loss of feeling or power, numbness, paralysis, as of the numbing torpedo fish in Cicero; heaviness, drowsiness, as in Lucilius; and in Seneca lack of will, lethargy, sloth.[2][5][6]

In Ecclesiastical Latin it means torpor, dullness, inactivity, sloth.[7] English torpor is from it.[8]
