Thingummy

Part of speech: noun

Pronunciation: /ˈθɪŋəmi/

Definitions

1. An informal term used to refer to an object or thing when the specific name is unknown or forgotten
2. A casual word employed to name an item whose exact term is not recalled or is unimportant in context
3. A colloquial expression for any unspecified object when the proper word cannot be remembered

Etymology: The base is "thingum," itself a shortened form of "thingumbob" or "thingumajig," and the ending "-y" is a familiar English diminutive, the same one that turns "doggy" or "Johnny" into friendly, informal forms. Adding it gives a playful, chatty tone to a word that is already a stand-in for a noun the speaker cannot retrieve. The family of words it belongs to shows how these placeholders multiply. "Thingamabob" and "thingamajig" are close relatives, each built on the same idea of "thing" plus a nonsense-sounding tail, and all of them serve the same purpose: naming an object without naming it. Speakers reach for these forms when a gadget, tool, or part is on the tip of the tongue, and the more casual the setting, the more likely the word is to appear.

Synonyms: thingamajig, whatchamacallit, doohickey, gizmo, widget
