Register: formal and informal English

Shift between formal, neutral and informal English: vocabulary, grammar and tone for emails, essays, speeches and chat.

In this lesson you will

  • Recognise features of formal and informal register
  • Rewrite texts in a different register
  • Choose register for audience and purpose

Learn

Register is the level of formality. Formal: longer Latinate words (obtain, commence, assist), passive and impersonal structures, no contractions, complete sentences. Informal: phrasal verbs (get, start, help out), contractions, ellipsis, direct you.

Examples: We regret to inform you that… (formal) / Sorry, but… (informal). Should you require further information… / If you need anything else…

Neutral English is correct for most workplace emails and many articles — polite, clear, not stiff.

Mismatch errors: Hey Professor, gimme an extension pls (too informal) or I would be most grateful if you could pass the salt (too formal). Consider audience, purpose, medium.

Examples

  • Formal: Please do not hesitate to contact us should you have any queries.
  • Neutral: Let me know if you have any questions.
  • Informal: Any questions, just shout!
  • Formal: The meeting will commence at 9. / Informal: We’ll kick off at 9.
