Pronunciation

  • IPA: /ˈsɛsˌpuːl/[1]

Etymology

Its origin is uncertain.[2][3][4] The usual explanation is that it is inherited from Middle English suspiral (“vent, breathing hole; drainpipe; settling tank”),[5][2][3][6] borrowed from Old French souspirail (“air hole, vent”),[5][2][7][8] from souspirer (“to breathe, sigh”), from Latin suspīrāre (“to breathe deeply, sigh”) (see suspire).[5][2][3][7] Its variant cesperalle (1583) was altered by association with pool.[5][2][3][7][8] Others take the second element as original and derive the first element from recess,[9][3][4] from Italian cesso (“privy”),[10][4] or from dialect suss (“hogwash”);[2][4] the early spelling cestpool has also suggested cistern.[3][4]

Earliest recorded meaning

A small pit in the bottom of a drain, under a grating, to catch sand and gravel (1583 in the OED, as cesperalle;[11][2] cestpool 1671 in Barnhart).[2]

Semantic evolution

Merriam-Webster's Word Histories calls the word “a veritable reservoir of etymological murk”.[4] From 1782 it was a well sunk to receive the waste from a privy or sink, letting the liquid soak away.[11][6] The figurative sense, a filthy or morally corrupt place, as in a cesspool of iniquity, is from 1837.[11][10][12] Cesspit was formed from it in the 19th century.[13][8]
