Characteristics of the formal letter

There are a number of features that distinguish a formal letter. Here are some of the elements of a traditional formal letter:

When writing a formal letter, the primary intention is to inform or communicate about something. This means that it is not used to send greetings or to initiate a conversation between two people. It is only intended to give notification of something important.

Sometimes, it may happen that when writing a formal letter you do not know the addressee. For example, if you want to send a letter of complaint to a company for a bad service provided, it is likely that the recipient of your letter is unknown to you. On the other hand, if your letter is addressed to your boss, there may be a certain degree of closeness.

The language used when writing a formal letter should be, as the name implies, formal. Use well-constructed phrases and sentences, with a broad, jargon-free vocabulary.

The expressions you will use when writing a formal letter should convey respect between the sender and the recipient. You may find yourself annoyed when writing a formal letter of complaint, however, you cannot use vulgarisms or expressions that may be considered disrespectful. This takes away from the seriousness of your letter.

You should make sure that your letter is not too long. Generally, those who receive this type of documents are very busy people who cannot take the time to read very long texts. Preferably, it is better to opt for a short and precise formal letter with the information you wish to communicate.

Spelling mistakes and grammatical errors are prohibited in a formal letter. You must be extremely careful and proofread your text as many times as necessary, otherwise, the recipient may detract from the validity of your letter.

Although in informal letters it is common to add a postscript at the end of the document, it is not one of the elements of a formal letter, so we recommend you not to do it.

It is best if your formal letter is written on a computer. We recommend using a font that is easy to understand, such as Arial or Cambria. Also, take care of the spacing between lines, the correct use of margins and indentation.

When printing your formal letter, you should use a suitable type of paper such as bond paper. You should also take care that your letter does not have stains or wrinkles.

Before ending your formal letter, you should add a small farewell paragraph in which you can emphasize the main idea of the text. You should also include cordial expressions, such as kind regards, cordial greetings, best regards, etc.
