/ ˌsəbstənˈtīvəl/ adj.
A grammatical term that in the Middle Ages
included both NOUN
and adjective, but later meant noun exclusively. It is not usually found in later 20c English grammars. In such languages as Latin and French, the equivalent terms serve to distinguish the use of LATIN nomen
, French nom
(etc.) as ‘name’ from the grammatical use as ‘noun’, a distinction which is unnecessary in English. However, the term has been used to refer to nouns and any other parts of speech serving as nouns (‘the substantive in English’). The adjective local
is used substantively in the sentence He had a drink at the local before going home
(that is, the local public house).
