- (grammar) More loosely, the use of unrelated (or distantly related) words for semantically related words which may not share the same lexical category, such as father/paternal or cow/bovine.
Strictly speaking, suppletion in linguistics refers only to inflection, such as good/better, which are both adjectives, and this is the most frequent use. It is also used in the looser sense of semantic relations without etymological relations (or with distant etymological relations) such as father/paternal, where these are noun/adjective. However, this latter use is significantly less common and may be considered incorrect.
