The document outlines the typical structure and components of a formal letter, including the greeting, opening paragraph, body, signalling the end, closing, and signature. It notes that the greeting should include "Dear" followed by the recipient's title and name if known, or "Sir," "Madam," or "Sir or Madam" if unknown. The opening paragraph should state the reason for writing clearly. The body can have 1-3 paragraphs providing relevant information. The letter should signal its ending before closing with "Yours sincerely" or "Yours faithfully" and the writer's printed signature.
