adnoun
LowTechnical/Linguistic
Definition
Meaning
An adjective used as a noun; a word that functions adjectivally but appears where a noun is expected in a sentence.
In historical and linguistic contexts, it may refer to adjectives more broadly, but in modern descriptive linguistics, it specifically denotes adjectives used in nominal positions (e.g., 'the poor', 'the beautiful').

Semantic Notes

- Avoid direct translation; Russian doesn't have an exact equivalent term in everyday grammar.
Common Mistakes
- Using 'adnoun' to mean any adjective.
- Confusing it with 'adverb'.
