Forms
prōmptus (feminine prōmpta, neuter prōmptum, comparative prōmptior, superlative prōmptissimus); first/second-declension adjective[1] It is sometimes spelled promtus, especially in early editions.[2][3] The noun prōmptus (fourth declension) is used almost only in the ablative, in prōmptū.[2][1]
Etymology
The adjective is the perfect passive participle of prōmō (“to bring out”), and the noun is formed from the same verb with the suffix -tus.[2][1] prōmō is prō- (“forth”) and emō (“to take”),[1] which de Vaan traces to Proto-Italic *eme/o- and Proto-Indo-European *h₁em-e/o- (“to take”), cognate with Lithuanian imti (“to take”).[4]
Earliest recorded meaning
Köbler first records it in Plautus.[5]
Semantic evolution
The adjective prōmptus is “ready to hand, available” (Cicero), “plainly visible, manifest”, and of tasks “easy, practicable”, with prōmptum est “it is easy”.[2][1] Of people it is “quick, prompt, active, keen”, of qualities “ready” (Sallust: prōmptam audāciam), of speech “fluent”, and “quick to help”; with ad or in it is “inclined to, ready for”.[2][1]
The noun lives on in the phrase in prōmptū, “at hand, at one's disposal” (Accius), “in full view” (Cicero: nature put the honourable parts of the body in prōmptū), “obvious”, and “within one's power”.[2][3][1]
Church Latin glosses the adjective “prompt, willing, visible, quick” and the noun “visibility, readiness”.[6] English prompt comes from the adjective in the mid-14th century.[7]
