What does foetor mean?
Foetor is a formal noun denoting a strong, offensive smell — the kind of rank, clinging odour given off by decay, infection, or accumulated filth. It carries an inherently repulsive connotation and is used almost exclusively in elevated or technical prose: medical writers may describe the foetor of a suppurating wound, while novelists evoke the foetor rising from a slum courtyard or an abandoned hold. The word derives directly from Latin fētor, meaning stench, and shares its origin with "fetid", the familiar adjective for something foul-smelling. Two spellings survive: "foetor", the traditional British form preserving the Latin-derived "oe" digraph, and "fetor", the simplified American spelling now dominant worldwide. Because everyday language reaches naturally for "stink" or "stench", choosing "foetor" signals deliberate gravity or clinical precision. It remains a useful word for anyone wanting to describe bad odours with unusual authority.
nounA strong, offensive smell; a foul or rank odour, especially one arising from decay, disease, or uncleanness.
- A foul, offensive smell, especially one produced by decomposition, infection, or filth.
"The foetor of the long-abandoned house struck them the moment they forced open the door."
"The ward was heavy with the foetor of gangrene."
"A foetor of rotting seaweed hung over the harbour at low tide."
The plural is rare since multiple distinct foul smells are seldom enumerated; the singular is almost always sufficient.
"The report catalogued several distinct foetors emanating from the refuse heap."
Before modern labs, doctors literally sniffed for foetor hepaticus — a sweetly rotten breath odour that signalled a failing liver.

Etymology of foetor
Foetor comes straight from Latin fētor, meaning a foul smell or stench, derived from the verb feteō, "to stink". The same root gives English "fetid" and its relatives, which entered English by way of descriptions of putrefaction in early scientific and medical texts. The word was adopted into English in the seventeenth century as anatomists and physicians sought precise vocabulary for pathological smells. The American spelling "fetor" reflects the general simplification of "oe" digraphs in English orthography, while "foetor" preserves the older learned form.
How foetor is actually used
Formal and literary in register; largely confined to medical writing and older descriptive prose. The spelling "foetor" is chiefly British; American usage strongly prefers "fetor", and even in Britain the unligatured spelling is increasingly common.
Easily confused with foetor
"Fetor" is simply the standard American spelling of the same word, while "foetor" is the traditional British spelling with the "oe" digraph.
