Other forms: addressees
The person who receives a letter in the mail is an addressee. If you're mailing a birthday gift, be sure to write the addressee's name and address clearly on the package!
Whenever you send something to a particular address, you indicate an addressee. If you send your best friend a postcard from Hawaii, you'll include her name, street number, city, state and zip code, making her the addressee. Adding -ee to the end of a word is one way to indicate the recipient of an action; along with addressee, words like appointee and employee also use this suffix.
