In English there are many ways to begin and end a letter according to the person you are writing to.
Salutation or greeting:
Dear Sir or Madam,
If you do not know the name of the person you are writing to, use this. It is always advisable to try to find out a name.
Dear Mr Jenkins, Dear Mrs Johnson
If you know the name, use the title (Mr, Mrs, Miss or Ms, Dr, etc.) and the surname only. If you are writing to a woman and do not know if she uses Mrs or Miss, you can use Ms, which is for married and single women.
Dear John, My dear(est) Jamie
If you’re writing to a friend or family member.
Ending a letter:
Yours Faithfully, Yours Sincerely, Your truly
All the best, Love from…, I can’t wait to see you/ hear from you, Eee you soon, Take care, I look forward to hearing from you/ seeing you
In a formal letter, remember not to use informal language like contractions.
Don’t forget your signature.
