- decrease:  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 dē-, denoting reversal of a previous condition, and crēscēre ‘grow’ (source of English crescent and a wide range of other words).
=> crescent, croissant, increase
