substraction
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.
