What mastery looks like

  • Generate synonyms and antonyms for given words and explain subtle differences between synonyms, e.g. happy/joyful/ecstatic differ in intensity
  • Use a thesaurus to find synonyms and select the most precise word for a given context, e.g. choosing 'sprinted' rather than 'ran' to convey speed
  • Replace overused words in writing with more precise synonyms and explain how the substitution changes the tone or emphasis

Check your understanding

When Antonyms & Synonyms is writing, can they swap out a basic word for a more precise one — for example, replacing "happy" with "elated" or "said" with "whispered" — to make their meaning clearer?
