promptly
UK: /ˈprɒmptli/ | US: /ˈprɑːmptli/
adv. without delay; immediately
adv. at exactly a specified time; punctually
The word "promptly" derives from the Latin promptus (meaning "brought forth, ready"), via Old French prompt. The root "prompt" retains its core sense of speed or readiness, while the suffix "-ly" transforms the adjective into an adverb. Historically, "prompt" was used in theatrical contexts (e.g., a "prompter" who ensures actors deliver lines without delay), reinforcing its association with timeliness. The adverb form emerged in Middle English, solidifying its modern meaning of immediate action or punctuality.
