is a way of arranging all the basic letter parts; there are 3 major letter formats used;
1-Block format-is each letter part begins at the left margin, the main advantage is quick and efficient preparation.
2-Modified block format-Same as block except that the date, complimentary close, and signature block start near the center of page; this format mix preparation speed w/traditional placement of letter parts; looks more balanced
3-Simplified format- Instead of using salutation, this format often weaves the reader's name into the first line or two of the body and oftern incudes a subject line in capital letters. Format is convienient when you don't know the readers name, but its very impersonal
