4.2The three registers

Everything in the letter depends on one decision made in the first ten seconds: who am I writing to? Get this wrong and even a well written letter loses marks.

RegisterWho you are writing toSignal in the question
FormalSomeone you do not know, by role: a manager, a company, a councilWrite to the manager, to the company, to the editor
Semi-formalSomeone you know in an official relationship: your landlord, your teacher, your neighbourWrite to your landlord, your supervisor, your neighbour
InformalA friend or family memberWrite to a friend, to your cousin, to your former classmate

Openings and closings, which must match

RegisterOpeningClosing
Formal, name unknownDear Sir or Madam,Yours faithfully,
Formal, name knownDear Mr Khan, / Dear Ms Adams,Yours sincerely,
Semi-formalDear Mr Khan, / Dear Mrs Adams,Yours sincerely, / Best regards,
InformalDear Sara, / Hi Omar,Best wishes, / All the best, / Love,
  1. Never write Dear Sir or Madam and then sign Yours sincerely. The pair is fixed.
  2. Never use a first name with Mr or Ms. Dear Mr Ahmed is only correct if Ahmed is the family name.
  3. In an informal letter you may use contractions such as I'm and don't. In a formal letter, write them out in full.
  4. Do not write your address, the date or a subject line. They are not required and they waste time.
