Synonym discussion

Sense: adjective/2

All four words describe something done or used by one person, but they differ in scope and register. 'One-man' is the most established compound and appears in fixed phrases like 'one-man show' (sense 1) and 'one-man operation' (sense 2), though some speakers avoid it in gender-sensitive contexts. 'One-person' is a direct gender-neutral substitute that works in most of the same slots, but it sounds less natural in traditional collocations like 'one-person show' (still acceptable but less common). 'Solo' is broader: it can describe an activity ('solo performance', 'solo business owner') and even a legal status ('solo parent'), and it carries a positive connotation of independence. 'Single-handed' focuses on the effort rather than the structure; you might complete a project 'single-handed' but the business is still a 'one-man operation' or 'solo practice'. For a learner, 'solo' is the safest all-round choice, while 'one-man' is best reserved for established compound-noun contexts.

Common collocations

Etymology

The compound 'one-man' dates from the early 1800s, formed from the numeral 'one' and the noun 'man' to describe something involving a single person. The most familiar use, 'one-man show', appeared in the theatre world in the mid-19th century, and the pattern later extended to businesses, vehicles, and equipment. A related colloquial term, 'one-man band', originally referred to a street musician playing several instruments at once, then broadened to mean anyone doing many jobs alone.
