Etymology: "Nudger" is simply "nudge" with the agent suffix "-er" attached, so it names a thing or person that nudges. The base verb "nudge" is an older English word, probably of imitative origin, and the suffix "-er" has long been used to turn verbs into nouns for doers or instruments, as in "baker" or "hammer." The noun has its most familiar use in the sense of a device or agent that gently prompts, such as a nudger in a crowd or a figurative nudger that encourages someone toward a decision. Its meaning follows the verb closely, since the core idea is a light, deliberate push rather than a hard shove.

Synonyms: prompter, reminder
