Nonsingle

Nonsingle is a term used in English to describe someone who is not single, typically meaning that the person is in a romantic relationship or otherwise committed. It is not widely established in formal dictionaries but appears in informal writing, online profiles, and discussions as a concise way to indicate that a person is partnered.

The word is formed by adding the prefix non- to single, yielding a negation that signals a status distinct from being single. It carries a neutral, matter-of-fact connotation and is often used in casual contexts, such as dating apps or social media bios, where users may choose between statuses like single, in a relationship, or nonsingle.

Usage of nonsingle varies by platform and region; some readers may find the term awkward or redundant, since "in a relationship" is the common conventional phrase. In many settings, more standard labels remain preferred, while nonsingle can serve as a lightweight or tongue-in-cheek alternative.

Related terms include partnered, in a relationship, taken, and not single. The term’s novelty means it can appear as a playful or experimental descriptor rather than a formal category.
