Determiner

In natural language, a determiner, also called a determinative (abbreviateddet), is a word or affix that is used with/precedes a noun to express its reference. Examples in English include articles (the and a/an), demonstratives (this, that), possessive determiners (my,their), and quantifiers (many, both). Not all languages have determiners, and not all systems of grammatical description recognize them as a distinct category.
