Pronunciation: [fɹˈa͡ʊst] (IPA) 
The word "frowst" is a somewhat uncommon term that refers to a stuffy, close atmosphere in a room. The spelling of this word may seem unusual, but it is actually phonetically accurate. The IPA phonetic transcription for "frowst" would be /frɔːst/. The initial "fr" sound is followed by the "ow" diphthong, then the "s" and "t" sounds at the end. So while "frowst" may not be a common word, its spelling is in line with its pronunciation.
Frowst, in its noun form, refers to a stuffy or stale atmosphere, particularly in a confined or poorly ventilated space. The word is often used to describe the feeling that arises when air in a room becomes stagnant and stale, perhaps due to a lack of ventilation or excessive warmth. This stuffy atmosphere can seem unpleasant and suffocating.
As a verb, frowst means to stay or remain in a confined space, often for a long duration. It implies a sense of being cooped up or trapped in close quarters. Frowst can also describe the act of making a place smoky or stuffy by means of heating or overcrowding, thus intensifying the stagnant environment.
The term "frowst" can be commonly associated with spaces such as small rooms, basements, or old buildings that have insufficient air circulation. It is generally connected to a feeling of discomfort and a desire for fresh air.
In a figurative sense, frowst can be used to describe a state of being mentally or creatively stifled, indicating a lack of fresh ideas or inspiration. The word can be employed to convey a sense of claustrophobia, both physically and mentally, representing the need for change or a fresh perspective.
Overall, frowst embodies the notion of a stagnant and oppressive state, whether in terms of physical atmosphere or mental condition.
The word "frowst" has a somewhat unclear etymology. It is believed to have originated as a blend or alteration of two older words: "frost" and "fust".
"Frost" can refer to a coating of ice crystals or cold temperature, reflecting the Old English word "forst" and its Germanic roots.
"Fust", on the other hand, is an obsolete word that typically referred to a moldy or musty smell. It can be traced back to Old French "fuste" meaning "stinking cask" or "wine cask".
The blend of these two words, "frowst", seems to have come into use in the late 18th century, particularly in British English. It initially referred to a close, stuffy, and ill-ventilated atmosphere, often associated with the smell of decay or mold.
