Writing an Informal Letter


Informal writing might not exactly be rocket science, but it still requires knowing some basic knowledge of the principles and rules that cover general letter writing approaches. Whether you are writing to a friend to share your experience of a recent trip, or writing to thank your high school tennis coach for the useful practice that you are now polishing up at college, or inviting an international student from Europe you made friends with while on vacation to come visit you, there are general guidelines concerning the structure and style of an informal letter with which you need to get acquainted.

There are several basic situations when an informal is written.
