Oncewider

Oncewider is a neologism used in informal English to describe a phenomenon in which a single action, event, or initiative broadens the reach, participation, or audience beyond what was previously possible. The term functions as a noun and is often used attributively, for example "a oncewider outreach effort." It has no official definition in major dictionaries and remains primarily within online discourse and occasional editorial commentary.

Etymology: Oncewider blends once and wider. Early known uses appear in English-language blogs and discussion forums from the 2010s onward, with varied capitalization and spelling (oncewider, OnceWider). It is not standardized across sources.

Usage: In digital culture and social analysis, oncewider is used to describe virality effects where a single post or event expands a community or audience beyond its initial boundary. In urban planning or policy discussion, it can denote a program or intervention that widens participation after a first success. In product or business contexts, it may describe a feature or campaign that opens new markets following a single release.

Reception: The term remains informal and is not widely adopted in formal scholarship. Some observers treat it as a descriptive shorthand rather than a defined technical term, and its interpretation can vary by context.
