Also known as suppletive

In linguistics and etymology, suppletion is traditionally understood as the use of one word as the inflected form of another word when the two words are not cognates. For those learning a language, suppletive forms will be seen as "irregular" or even "highly irregular". For example, go:went is a suppletive paradigm, because go and went are not etymologically related, whereas mouse:mice is irregular but not suppletive, since the two words come from the same Old English ancestor.
