Differences and uses of formal and informal writing.

Context as a Style Compass

The choice between a formal or informal writing style is not arbitrary; it depends directly on the purpose of your communication, the audience you are addressing and the context in which you find yourself.

Writing a professional e-mail to a client is not the same as sending a quick message to a friend.

Using an informal tone in a job application, for example, could project a less-than-serious image and hurt your chances.

Therefore, knowing how to distinguish and apply the right style in each situation is a fundamental communication skill that allows us to convey our messages effectively and be perceived in the right way in every interaction.

Formal Style: Structure, Accuracy and Objectivity

Formal writing is the standard in professional, academic and official document contexts, where a serious, structured and objective tone is required.

Its main characteristics include the use of a sophisticated vocabulary, avoiding colloquialisms and everyday expressions.

Sentences tend to be longer and more complex, with impeccable grammar and the use of connectors such as "therefore" or "however" to link ideas.

For example, in an academic report, instead of writing "We found that people don't like advertising," you would use a formula such as "Research indicates that excessive advertising can lead to consumer dissatisfaction."

The Informal Style: Approachability, Emotion and Naturalness

The informal style is used in casual communications with friends, family or people you trust, and its main characteristic is that it closely resembles spoken language.

It is characterized by a conversational tone and the use of everyday language, with shorter, simpler and more direct sentences.

In addition, this style allows for a much more personal and emotional tone, where humor, opinions and feelings have a place.

A clear example is a text message to a friend; instead of a formal "Would you be available to chat later?", a simple "Hi, free to chat later?" is much more appropriate.

When and Where: Applying the Correct Style.

Knowing when to use each style is crucial for effective communication. Formal writing is the right choice for:

• Business emails and professional communications.
• Academic papers, essays and theses.
• Official and legal documents.
• Job applications and cover letters.

On the other hand, informal writing is most appropriate for:

• Text messages and chats with friends or family.
