Synonym discussion

Sense: noun/2

All four words refer to someone who directs other workers, but they differ in industry and formality. 'Foreman' is the most general term for a worker who leads a team, used across construction, manufacturing, and trade settings. 'Supervisor' is broader still and works in offices, schools, and factories — it carries a slightly more formal tone. 'Crew chief' is specific to film, television, and motorsports; it implies a small, specialised team rather than a large workforce. 'Overseer' is historical or agricultural and can sound old-fashioned outside those contexts. 'Luna' sits closest to 'crew chief' but is even more restricted — you will almost only hear it on film sets or construction sites. For example: 'The foreman walked the factory floor' sounds natural; 'The luna walked the factory floor' would strike most English speakers as odd or unclear.

Etymology

LatinEnglishItalian

Borrowed from Latin 'lūna' meaning 'moon'. In medieval alchemy, each classical planet was linked to a metal — the moon was paired with silver, so alchemists writing in Latin referred to silver as 'luna'. The second meaning, 'foreman', comes from Italian film-industry jargon, where 'luna' (originally 'moon') developed into a term for the crew chief through a chain of trade usage that is not fully documented.
