The letter begins with an address followed by a comma. (from a new line, skipping a line)
Dear Sally,
At the beginning of the letter, the author usually:
Thanks the addressee for the previously received correspondence:
Thanks for...
Many thanks for...
How nice of you ...
I was awfully glad to get your letter...
- apologizes for not writing earlier:
I must apologise for not writing...,
I really should have written sooner....
In this part, all aspects specified in the assignment should be disclosed. Be sure to ask three questions about the mentioned information at the end. Each paragraph is written on a new line, skipping a line.
This phrase depends on the degree of closeness between the author and the addressee, and is always followed by a comma. (from a new line, skipping a line)
