Forms

tremulus (feminine tremula, neuter tremulum); first/second-declension adjective[1]

Etymology

It is formed from tremō (“to tremble”) with the suffix -ulus.[2][3][1] De Vaan traces the verb to Proto-Italic *trem-e/o- and Proto-Indo-European *tr(e)m- (“to tremble”), cognate with Umbrian tremitu (“let him scare”), Ancient Greek τρέμω (trémō, “to tremble”) and Lithuanian trìmti (“to tremble”).[3]

Earliest recorded meaning

De Vaan dates it from Plautus,[3] who has a “trembling old woman” in the Curculio.[2][4]

Semantic evolution

It is trembling or shaking, of people and parts of the body, from age, illness, weakness, fear or cold, as Juvenal's feet that cannot stand.[2][4] Of a voluntary movement it is shaking or wriggling, as Catullus' baby boy rocked in his father's arm.[2] Of things it is quivering, as Catullus' creaking bed; of light flickering, as Ennius' trembling light; and of sound quavering, as the mother bird's cry in Cicero's verse.[2][4]

Lewis and Short call it poetic and post-Augustan.[4] In Late Latin, from the 6th-century Plinius Valerius, it is also a noun for the aspen,[1] and medieval Latin keeps it as “trembling poplar”.[5] English tremulous comes from it, from the 1610s.[6]
