Informal vs. Formal English: Understanding the Difference

Updated: Oct 2, 2023

As a versatile language, English offers various ways to express ourselves, depending on the situation and audience. Two primary styles of English that we often encounter are informal and formal. Let's explore the distinctions between these two styles.

Formal vs Informal English

Informal English

Informal English is like your friendly next-door neighbour - relaxed, casual, and easy-going. It is the language you use with your friends, family, and people you are close to. Here are some key characteristics:


Informal English is full of contractions like "I'm," "you're," "they're," etc. These make sentences shorter and more conversational. For example, "I'm going to the store" instead of "I am going to the store."


Informal English embraces colloquial expressions and slang. Phrases like "What's up?" or "Chill out" are common in informal conversations.

First and Second Person Pronouns:

Informal language often uses first and second person pronouns like "I," "you," and "we." It is all about making the conversation personal.

Casual Vocabulary:

You might use simpler and more everyday words when speaking informally. For instance, "buy" instead of "purchase" or "kid" instead of "child."

Sentence Fragments:

Informal English allows for sentence fragments like "Got it" or "No way!" These are acceptable in casual settings but not in formal writing.

Formal English

Formal English is more like the stern professor in a lecture hall - precise, structured, and authoritative. It is the language of academic papers, business reports, and official documents. Here's what sets it apart:

No Contractions:

Formal English avoids contractions. You would say, "I am" instead of "I'm," and "you are" instead of "you're."

Avoiding Colloquialisms:

Colloquial expressions and slang have no place in formal English. Instead, opt for more standard and neutral language.

Third Person Pronouns:

You will find the use of third person pronouns like "he," "she," "it," "they," and passive voice more common in formal writing. This keeps the focus on the subject matter rather than the writer or reader.

Sophisticated Vocabulary:

In formal English, you would prefer sophisticated words and avoid their simpler counterparts. "Acquire" instead of "get" or "adolescent" instead of "teenager" would be typical choices.

Complete Sentences:

Formal writing requires complete and well-structured sentences. Avoid sentence fragments and ensure a logical flow of ideas.

Choosing between informal and formal English depends on the context. Use informal language when chatting with friends or writing personal emails. Formal language, on the other hand, is crucial for academic, professional, and official communication.

In summary, mastering the balance between informal and formal English is essential for effective communication in various situations. Being aware of these differences allows you to adapt your language to the appropriate setting, ensuring your message is conveyed accurately and respectfully. So, whether you are having a casual chat or crafting a formal document, understanding when to employ each style will enhance your language skills.
