How to Write a Letter

The art of writing a letter takes practice, knowledge about proper form and the ability to put into words your feelings, thoughts, and/or ideas. If you learn the basic parts of a letter, it will help you to create letters for a variety of occasions. The Presentation of the Letter
The presentation of the letter can be hand-written for less formal letters that are addressed to friends and family members, especially thank-you letters. In the case that you have illegible handwriting, you may want to consider typing the letter in these cases, although proper etiquette dictates against this type of behavior.
Formal letters which are written on behalf of businesses to or professional contacts should remain typewritten and grammatical and spelling error free. These types of letters should be legible and professional and therefore typing the letter is one of the most effective ways to ensure that the letter demonstrates a professional appearance through the entire course of the letter, thereby creating a positive impression on the recipient of the letter.
As well as outward presentation, it is important to determine the tone which will be written in the letter, including a professional tone or a tone that will be taken with friends or family members in a more informal setting. Read through the letter once it has been completed to ensure that the tone remains the same. The tone can be adjusted based on the language which is used through the letter, as well as the greetings (familiar as opposed to formal).
