Formal and informal language · Grade 4

In Grade 4 you learn: contractions and full forms; slang and chatty phrases.

We choose our words for the reader. Informal language is relaxed and chatty, for friends and family: contractions, slang and phrasal verbs. Formal language is careful and polite, for people we don't know, schools, companies and exams: full forms, precise words and longer sentences.

Key facts

  • Contractions are informal; full forms are formal: can't → cannot, we're → we are.
  • Slang and chatty phrases (gonna, awesome, grab your stuff) never go in formal writing.
