Formal Letter and Informal Letter: Features, Elements and Characteristics

We explain what formal letters and informal letters are, the differences between them, their characteristics and elements of each one.

What is a formal letter and an informal letter?

A letter is a traditional form of communication between people , in which a sender writes a text and sends it to a receiver. The letters can be formal or informal according to their function and the relationship that exists between the sender and the receiver.

In a formal letter, the relationship between the two people is distant because it usually occurs between people who do not know each other personally. A formal language is used, then, and they are letters that usually have a predetermined structure. They can have labor, commercial purposes, among others.

On the other hand, the informal letter is one in which both parts of the communication have an affective or close relationship . In this case, the issuer is allowed to choose the structure and elements of the letter, and informal language is usually used. They are written for various purposes such as: invitations, greetings, thanks, among others.

Letters are one of the oldest means of communication and today they are increasingly out of use due to new technologies such as email and chat.

They are written that are sent in an envelope that includes the name and address of the recipient on the front and the sender’s name and address on the back. They are usually sent by mail or can be delivered by hand by a courier or by the same issuer.

Differences between a formal letter and an informal letter

Some of the main differences between a formal letter and an informal letter are:

  • Sender and receiver . In formal letters, the relationship between the sender and the recipient is mediated by a professional, labor or intellectual activity. In informal letters, the relationship between sender and receiver is one of closeness or affection (they are usually family or friends).
  • Language . The type of language used in a formal letter is formal and aloof and cannot have spelling and grammar errors. An informal letter allows for colloquial language because there is a close relationship between the sender and the receiver.
  • Objective . The formal letter is usually written for a specific purpose, for example, to express interest in a job, to arrange a meeting or to make a complaint or request. Informal letters are usually written to establish contact with another person and do not necessarily have to include a request or specific information.
  • Structure . The formal letter maintains an internal structure that does not allow to ignore any section or to change it of place, the elements that constitute this type of letter are structured in advance. In informal letters the structure is freer and all the elements that the writer deems necessary can be included.
  • Extension . The formal letter usually has a short length, since only its objective is detailed in its body. Informal letters can be as long as the issuer wishes.
  • Elements . Formal letters differ from informal letters by their constituent elements. They should include, among other things, a heading, a formal salutation, an introduction, a body of the letter and a final salutation with signature and clarification. For its part, the informal letter usually includes greeting, body and final greeting. Some may include postscripts and clarifications.
