Pronunciation

  • UK: /dɪˈtɜːd͡ʒənt/[1]
  • US: /dɪˈtɝd͡ʒənt/[1]

Etymology

It is borrowed from Latin dētergēns (“wiping off”), the present participle of dētergeō (“to wipe away, cleanse”),[2][3][4][5][6] formed from dē- (“off, away”) and tergeō (“to rub, polish, wipe”).[3][4][7][6] Merriam-Webster and Barnhart allow that it came partly through French détergent,[8][4][9] and Klein derives it from French;[10] the OED notes that the French word is recorded in Cotgrave in 1611 and in the dictionary of the Académie only from 1835.[2] Etymonline calls the origin of tergeō uncertain;[3] Barnhart makes it cognate with Ancient Greek τρώγω (trṓgō, “to gnaw”), from an extension of the Indo-European root Proto-Indo-European *ter- (“to rub”) seen in terō (“to rub”).[4] The past participle of the Latin verb is the source of terse.[7]

Earliest recorded meaning

As an adjective, cleansing, purging: 1600, in Surflet's translation of the Maison Rustique of Estienne and Liébault.[2] Barnhart and Merriam-Webster date the adjective to 1616.[4][8]

Semantic evolution

The word was at first a medical term, for something that cleansed wounds or the body;[3][7] Johnson (1755) gives the adjective as "that which cleanses", quoting Arbuthnot on food that should be "nourishing and detergent".[11] The noun, a cleansing agent, follows in 1676, in Wiseman's surgical treatises.[2][4][8] Its application to a synthetic chemical cleaner, as opposed to soap, which is made from fats and lye, is a 20th-century development,[7] recorded by 1932.[3] The noun is now used chiefly in this sense.[2][5]
