Pronunciation

  • /ˈfiːkəl/[1]

Etymology

It is formed from English feces + -al,[2][3][4] the OED taking it from Latin faex (“dregs”) with -al, and comparing French fécal.[5] The Merriam-Webster Unabridged derives it instead from Middle French fecal, from the Latin stem.[6] Etymonline describes the Latin noun, meaning grounds, sediment or the lees of wine, as of unknown origin.[2]

Earliest recorded meaning

Of the nature of feces, or containing them: about 1541, in Robert Copland's Questyonary of Cyrurgyens, a translation from Guy de Chauliac.[5] The Merriam-Webster Unabridged gives 1541,[6] Etymonline the 1540s,[2] and Dictionary.com 1535–45.[3]

Semantic evolution

The adjective is older than the sense "excrement" of the noun feces, which first meant dregs (about 1400) and was used for human excrement only from the 1630s, a sense not found in classical Latin.[2] The OED, in a definition first published in 1894, lists medical phrases such as faecal abscess, faecal fistula and faecal tumour.[5]
