Correspondence competency is an ability of paramount importance since we are all involved in writing letters. We write informal letters to our friends or family. We send formal letters to people who we may not know personally. There may be various reasons for writing a formal letter. One can write a letter to find out and share information, to apply for a job or to resign, to make a complaint or to say thank you for service and assistance, to make an invitation or to send an apology, etc. Formal letters for business communication and informal personal letters are composed in a different way. While there are almost no strict rules for an informal letter there are certain standards for formal letters writing which the addresser should know and follow. For those who do not know the conventions of formal letters and/or are not trained to do this writing can be really stressful and time consuming.
