What you'll learn

By the end of this lesson, you'll be able to write formal English for official letters, documents and announcements.

When do I use it?

Formal English is used in official letters, legal documents, announcements and academic correspondence. Its features:

  • No contractions: "I am", "we have", "it is".
  • Passive voice: "The decision was made" instead of "We decided".
  • Formal vocabulary: "request" (ask), "assist" (help), "inform" (tell), "purchase" (buy), "regret" (be sorry).
  • Full structures: "I would like to inform you that..." "Please find attached..."
  • No slang, no phrasal verbs, no "you" in impersonal documents: "Applicants must provide..."

How do I form it?

Structure

full forms + passive + formal verbs + precise connectors

  • I am writing to request further information.
  • The meeting has been rescheduled to Monday.
  • Applicants are required to submit their documents.
  • We regret to inform you that your application was unsuccessful.
  • Kindly note that the office will be closed on Friday.

Common mistakes for Spanish speakers

Warning

Spanish formal letters are MORE formal than English ones. "Sírvase", "se ruega" do not translate literally — "please" is enough. Do not use "Dear Sirs" for all genders (use "Dear Sir/Madam" or the name). Contractions are banned: "I'm writing" is wrong in a formal letter. And "inform you that" takes a clause, not "about": "inform you that the meeting is cancelled", never "inform you that the meeting is cancelled" with a wrong "about" → "inform you about the cancellation" (noun).

Hint

Full forms, passive, formal verbs. Keep it impersonal and precise. No contractions, no slang.
