Pronunciation

  • IPA (Classical): [ˈkae̯.nũː][1]
  • IPA (Ecclesiastical): [ˈt͡ʃɛː.num][1]

Forms

caenum n (genitive caenī); second declension[1]

Etymology

Its origin is unclear.[2][3] Walde and Hofmann linked it with cūniō “to defecate” and inquinō “to soil”, which would need an original o-grade *koino-, but de Vaan calls this formally impossible without speculative assumptions.[2] The same objection rules out a connection with Swedish dialect hven and Latvian svīnît (“to soil oneself”), and de Vaan thinks obscēnus is probably unrelated.[2] Wiktionary, after Pokorny, gives a root Proto-Indo-European *ḱweyn- (“to soil; mud”).[1][4]

Earliest recorded meaning

De Vaan dates it from Plautus, whose character wants to lure a young man out of the muddy filth of a brothel.[2][5] Köbler dates Plautus c. 250–184 BC.[4]

Semantic evolution

It meant mud, filth, slime, always with a sense of loathsomeness, as Cicero's saying that all filth smells bad.[5][6] It was used with a suggestion of moral uncleanness, figuratively of a sordid or low condition, as Livy's plebeian who was dragged from the mire to the consulship, and as a term of abuse for a person, “scum”.[5] Döderlein distinguishes lutum, the dirt of streets, and līmus, the mud of a river, from caenum, the mire of a swamp or sewer.[7]

In Medieval Latin it kept the senses mud, filth and moral corruption.[8][9] It survives in Italian and Portuguese ceno and Spanish cieno “mud”.[1]
