What does frowsty mean?
Frowsty is a chiefly British adjective describing a place — most often a room — that smells stale, stuffy, and unpleasantly warm because fresh air has not circulated through it. To call a space frowsty is to register a sensory complaint: shut windows, settled dust, and air that has been breathed and rebreathed. The word carries a mild, domestic distaste rather than strong disgust; a frowsty parlour or railway carriage calls for an open window, not an evacuation. It sits comfortably alongside near-neighbours such as stuffy, musty, and fusty, but retains its own distinct flavour of shut-in, lived-in airlessness. Largely unfamiliar to American ears, it remains a characterful fixture of British usage, appearing in fiction and everyday speech whenever a narrator wants to convey that particular staleness of a room left too long undisturbed. Its companion term frowst names the stale atmosphere itself.

Etymology of frowsty
Frowsty emerged as a distinctively British word in the latter half of the nineteenth century, apparently as an offshoot of the older term 'frowzy', which since at least the seventeenth century had described unkempt people and slovenly dress. Both words are of obscure origin; they may ultimately derive from an Old French root, though no definitive source has been established. From frowsty came the noun 'frowst', denoting the stale atmosphere itself.

How frowsty is actually used
Frowsty is chiefly British and informal-to-neutral in register; it is rarely encountered in North American English, where 'stuffy' or 'musty' are preferred. Its connotation is mildly unpleasant but domestic rather than offensive — it evokes stale air and neglect, not filth or decay.
Easily confused with frowsty
Frowzy describes unkempt, untidy people or their hair and clothing, while frowsty applies to stale-smelling rooms or spaces.
Fusty suggests the old-fashioned, mouldy smell of long-uncirculated air in old buildings or books, whereas frowsty covers any staleness from shut-in, unventilated air.
