Pronouns

English · Grammar & Punctuation · conceptual

Use personal, possessive, and indefinite pronouns correctly (e.g., I/me/my, they/them/their, anyone/everything), replacing nouns to avoid repetition

What mastery looks like

  • Replace a repeated noun with a pronoun: 'The dog was happy. He wagged his tail.'
  • Use I/me correctly in subject and object position in a sentence
  • Choose the correct possessive pronoun (my/his/her/their) to match the noun it replaces

Check your understanding

When Pronouns retells a story or describes what a friend did, do they use words like "he", "she", "they", or "his" correctly — instead of repeating the person's name every single time?
