Etymology: The noun "oncers" is a colloquial formation derived from the adverb "once," which means "one time." It emerged as a plural noun in informal English usage to denote people who have done something once or who are characterized by having experienced a particular event a single time. This kind of nominalization, turning a time-related adverb into a noun referring to a group, reflects a playful and flexible aspect of English word formation, often found in dialects or casual speech. The process likely began by attaching the English plural suffix "-s" to "once," treating it as a countable entity, even though "once" is originally an adverb without a plural form. This linguistic innovation allows speakers to refer collectively to individuals distinguished by a singular occurrence, such as "oncers" who tried an activity once or "oncers" who once belonged to a group. The exact origin is uncertain, but it fits into a broader pattern where time expressions become nouns—similar to how "twice" can sometimes be used nominally. This usage does not appear in formal or classical English dictionaries but thrives in regional dialects and informal contexts, often carrying a slightly humorous or affectionate tone. It illustrates how English speakers creatively stretch parts of speech to suit conversational needs, turning an abstract temporal concept into a tangible social category. While the pluralization of an adverb is unusual, it mirrors other playful formations in English where adverbs or other non-nouns take on noun-like roles for emphasis or categorization. The term likely arose in the 20th or 21st century, reflecting modern informal speech rather than historical lineage from Old or Middle English.
