English[edit]
Etymology[edit]
From Middle French substraction (compare modern French soustraction), from Old French substraction, from Medieval Latin substractio, derived from Late Latin substractus. Ultimately from Latin subtraho (“to pull out from under; to remove, to subtract”).
The use by non-native speakers arises by analogy with words such as French soustraction and Spanish sustracción.
