### sense in the lessons

In English grammar lessons (and SATs tests in England), pupils find determiners: articles (a, an, the), demonstratives (this, that, these, those), possessives (my, your, their), quantifiers (some, many, every) and numbers. A determiner goes before any adjectives: «the big red bus».

Countable: determiners. Trap: «this» is a determiner in «this book» but a pronoun in «I like this». «A» becomes «an» before a vowel sound: an apple, an hour, but a unicorn.

### In the corpora

- [My, your, his, her, our and their before a noun are called possessive determiners in school grammar.](https://md.mova.elamur.ai/free/en/corpora/school/english/27-word-classes-the-jobs-words-do/27/)
