Sense: adjective/1

All four words describe a lack of fresh air in an enclosed space, but they differ in nuance. 'Stuffy' is the most common everyday word; it suggests the air feels heavy and unpleasant from being confined. 'Airless' is more dramatic and implies a total lack of air movement — it is often used in descriptive writing. 'Musty' adds a damp, mouldy smell to the picture: a basement or old cupboard is musty, not just unaired. 'Stale' focuses on the quality of the air itself (e.g., 'stale cigarette smoke') rather than the space. In practice, a room can be both stuffy and unaired, but 'unaired' is the most neutral, factual label — it simply says no fresh air has entered, without the judgement carried by 'stuffy' or the smell implied by 'musty.'

Etymology

LatinFrenchEnglish

Formed in English by adding the negative prefix 'un-' (from Old English 'un-', meaning 'not') to 'aired', the past participle of the verb 'air' (to expose to fresh air). The verb 'air' came into Middle English from Old French 'airer' and ultimately from Latin 'aer' (air). The adjective 'unaired' has been used since at least the early 19th century to describe rooms and spaces not reached by fresh outside air.
