Letter writing is a form of communication where something structured is to be written. It enables the writer and the reader to refer to each other’s communication readily and so be able to retrieve information quickly. Letter writing can be personal letters between loved ones and friends or formal letters between business and commercial entities. Both personal and formal letter writing need to adhere to some particular rules.
When writing a letter a long story does not have to be written. The fact that information is exchanged regularly between the writer and reader should make it clear that brevity, structure, formal words, clarity and chronology are the attributes a letter should possess, particularly in a formal letter. In personal letters both formal words and informal words can be made use of.
