Final answer:
The enclosure notation is not a standard part of a letter's format. The standard part typically includes the return address, date, inside address, greeting, body of the letter, and closing. Enclosure notations are used for additional documents.
Step-by-step explanation:
The standard parts of a letter include everything except the enclosure notation. The key components of a letter typically consist of:
- Your return address: Including your name, street address, city, state, and zip code.
- Date: The current date written out in full.
- Inside address: This includes the recipient's name, title, organization or school name, and their full address.
- Greeting or Salutation: A polite opening such as 'Dear Mr./Ms. [Last Name],'.
- Body of the letter: This is where you communicate your message, written in a professional tone using an appropriate business font and formatting.
- Closing: A formal sign-off like 'Sincerely' followed by your signature and typed name.
Enclosure notations are used when additional documents are included with the letter, but they are not considered part of the standard parts of a letter's format.
