A determiner is a word, phrase or affix which modifies a noun phrase[glossary].

In English these can be [glossary]articles, possessive pronouns, and numerals.

In English, determiners include

  • articles (a, an, the)
  • numerals (including cardinal numbers (one, two, three…) and ordinal numbers (first, second, third…))
  • demonstratives (this, that, these, those)
  • partitives (some of, piece of, and others)
  • quantifiers (most, all, and others)
  • difference words (other, another),
  • possessive determiners (my, your, his, her, its, our, their).

In Australian Indigenous languages, determiners can include most of these, but not articles.
