English grammar: Determiners

What this grammar point covers

Determiners are words placed before nouns to give more information about which thing or how many things you are talking about. They include words like 'the', 'a', 'some', 'my', 'this', and 'each'.

When to use it

Use determiners in English to specify or describe nouns. They help show if you are talking about something specific or general, how many things, or who owns something.

Key forms

• 'the' (definite article)
• 'a', 'an' (indefinite articles)
• possessives: 'my', 'your', 'his', 'her', 'its', 'our', 'their'
• demonstratives: 'this', 'that', 'these', 'those'
• quantifiers: 'some', 'any', 'many', 'much', 'few', 'several', 'each', 'every', 'all'

Examples

Tips

• Remember: Use 'a' before words that start with a consonant sound and 'an' before words that start with a vowel sound.
• You cannot use more than one main determiner before a noun (for example, do not say 'the my dog').

Exceptions and edge cases

• Some nouns do not need a determiner, especially when talking about things in general (e.g., 'Dogs are friendly.').
• Uncountable nouns often use 'some' or no determiner at all.
