英文詞源


decrease
decrease: [14] Etymologically, decrease means ‘ungrow’. It comes from de(s)creiss-, the present stem of Old French de(s)creistre, which was a descendant of Vulgar Latin discrēscēre. This was an alteration of Latin dēcrēscēre, a compound verb formed from the prefix -, denoting reversal of a previous condition, and crēscēre ‘grow’ (source of English crescent and a wide range of other words).
=> crescent, croissant, increase
decrease (v.)
late 14c., from Anglo-French decreiss-, present participle stem of decreistre, Old French descroistre (12c., Modern French décro?tre), from Latin decrescere "to grow less, diminish," from de- "away from" (see de-) + crescere "to grow" (see crescent). Related: Decreased; decreasing.
decrease (n.)
late 14c., "detriment, harm;" early 15c. as "a becoming less or smaller," from Anglo-French decres; see decrease (v.).
