Dear Mr.

/dɪər ˈmɪstər/

Meaning

This is a formal salutation used at the beginning of a business letter or email. It must be followed by the man's last name (family name), not his first name. It is polite and respectful, making it perfect for writing to clients, managers, or people you do not know well.

    ✓ Dear Mr. Smith, (or Dear John,)

    The title 'Mr.' must be followed by the person's last name (surname), never just their first name.

  • ✗ Dear mr. Smith,

    ✓ Dear Mr. Smith,

    Both 'Dear' and 'Mr.' must be capitalized because they are part of a formal title and salutation.
