Basics on the topic Formal and Informal Language

To better communicate with people around us, we need to know the difference between formal and informal language. Learn about formal vs informal language using our video, activities, and formal and informal language worksheets.

Formal and Informal Language – Definition

First, let’s define formal and informal language.

  • Formal language is used when speaking or writing to adults, for school assignments, or when giving a presentation to a group of people. Formal language makes us sound more polite and respectful towards adults or people who we don’t know.

  • Informal language is used when communicating with peers, writing short stories, or sending emails and text messages to friends.

How do we know when to use informal and formal language? We use formal or informal language based on the situation and audience. For example, when greeting your teacher, you would say “Good morning, Mister Jones!”, and not “Hi! What’s up?” because the latter is an example of a very informal language that you can use with your friends.

Formal and Informal Language – Characteristics

When using formal language, we must make sure that we use complete sentences and follow all grammar rules. In most cases, we would use a serious tone, unless it is necessary to be conversational. We also use formal vocabulary and avoid contractions, slang, nicknames, and figurative language.

In contrast, informal language is casual and is used in our everyday lives. Informal sentences can be incomplete or loosely organized. We also use conversational vocabulary to make our language more natural. We can use contractions, slang, nicknames, and figurative language.

Use this chart to compare the characteristics of formal and informal language:

Formal Language Informal Language
Complete sentences Incomplete sentences
Proper grammar Loose sentence organization
Serious tone Casual tone
Formal vocabulary Conversational vocabulary
No contractions, slang,
nicknames, or figurative language
Contractions, slang,
nicknames, and figurative language are allowed

Formal and Informal Language – Examples

Now, let’s take a look at some examples of formal and informal language. Can you identify which sentence is an example of formal language?

Hello, guys! Wow! It’s cool to see you all here!

Good evening, everyone! It is a pleasure to have all of you here.

The second sentence is an example of formal language. The sentence is complete, the grammar and vocabulary are formal, and the tone is relatively serious. The first sentence is an example of informal language, because it uses conversational vocabulary like contractions and slang, and has incomplete sentences. The tone is very casual.

Here is another example. Can you identify the example of informal language here?

Dear Mrs. Lee, I am writing to let you know that I was not able to come to school last week because I was feeling sick. Can you please let me know if there is any homework I need to complete? Thank you.

Hi, Lee! Sorry I wasn’t at school last week. Was sick. Is there any homework for me? Thanx.

The second sentence is written informally. It uses casual language, contractions, and incomplete sentences. It would be more appropriate to use the first sentence when writing to a teacher. The first sentence is formal, it uses appropriate language, proper grammar, full sentences, and is more polite.

Formal and Informal Language – Summary

When communicating with others, we use formal and informal language. We can choose which language to use based on the situation and audience.

Formal language is used when speaking or writing to adults, completing school assignments, giving a presentation to a group of people. It makes us sound more polite and respectful towards adults or people who we don’t know. Informal language is used when communicating with peers, writing short stories, or sending emails and text messages to friends.

Now you can easily answer the question “What is formal and informal language?” and use appropriate language in your writing and speaking. For more practice, check out our video and activities.

Transcript Formal and Informal Language

Koko, will you listen to my art gallery opening speech? "Hey, everybody! Isn’t it so cool with all the fancy stuff here? Shout out to Koko! "She's crushing it with art!” "PIP! "You can't give a speech like that at a formal event!" Pip has a big speech to give for the art gallery opening and needs to learn about... Formal and Informal Language We can use formal or informal language to communicate with others. The situation and audience determine the type of speech we use. Formal language is used when writing or speaking with adults, an assignment for school, or giving a presentation to a group of people. Informal language is appropriate when communicating with peers, writing short stories, or sending text messages and emails to friends. When communicating formally, we must make sure our sentences are complete and follow all grammar rules. Most of the time, we use a serious tone, but we can be conversational when necessary. The vocabulary used is also formal. We avoid using contractions, slang, nicknames, and figurative language where possible. In contrast, informal language is very casual and used in our daily lives. The sentences may be incomplete or loosely organized. To make our language more natural, we use conversational vocabulary. This is where contractions, slang, nicknames, and figurative language are okay to use! Pip's speech was inappropriate for an art gallery opening. His current language is informal, so it would be acceptable among a group of friends. Let's take a look at how we can reword his speech and make it appropriate for the art gallery opening. First, he said, "Hey everybody!" "Hey everybody" is a very casual way of greeting friends. One way to make it more formal would be to say "Good evening, everyone.' His next statement, "Isn't it so cool with all the fancy stuff here?" was about how pretty the gallery looked with all the decorations. "Isn't," 'cool," and "stuff" are informal words. We can adjust the vocabulary to make it more appropriate for the occasion. The art gallery looks amazing on this special night. Next, he wanted to introduce Koko by saying... "Shout out to Koko." This informal statement could be changed to say specifically what he wanted to do. I am honored to introduce my friend, Koko. Finally, he wanted to compliment Koko's artwork by saying, "She’s crushing it with the art!" The expression "crushing it" is slang and needs to be changed. Instead, Pip should say... Koko is an extremely talented artist, and her artwork is amazing. While Pip prepares to give his formal speech, let's review. Remember... We can use formal or informal language to communicate with others. The situation and audience determine the type of speech we use. Formal language is used when writing or speaking with adults, an assignment for school, or giving a presentation to a group of people. Informal speech is appropriate when communicating with peers, writing short stories, or sending text messages and emails to friends. "Hey..." "Good evening, everyone. The art gallery looks amazing on this special night. I am honored to introduce my friend, Koko. "She is an extremely talented artist, and her paintings are beautiful."

    Solution

    The yellow words and phrases use slang, nicknames, contractions, and incomplete words. This is ok for informal language and conversations, and the words in blue are better for formal language.

  • Rewrite Pip's speech.

    Hints

    Pip's first line, "Hey everybody!" is a greeting. Can you find another greeting on the right side to match?

    Pip's line "Shout out to Koko!" is an informal way to introduce Koko. Can you find a more formal introduction for Koko on the right?

    When Pip says, "She's crushing it with the art!" what he means is that Koko's artwork is very good. Can you find a more formal version of this on the right side?

    Solution
    • Instead of hey everybody! Pip should say good evening everyone as the first version is too casual and friendly.
    • Instead of isn't it so cool with all the fancy stuff here? Pip should say the art gallery looks amazing on this special night as the words isn't, cool, and stuff are not formal enough.
    • Instead of shout out to Koko! Pip should say I am honored to introduce my friend Koko as the first version uses slang.
    • Instead of she's crushing it with the art! Pip should say Koko is an extremely talented artist and her artwork is amazing as the first version uses slang.
  • Define informal language.

    Hints

    Ki-ki Wala Wala is another version of the name Koko.

    Contractions are two words combined with an apostrophe, such as you're instead of you are.

    A more formal version of Hey! would be Hello.

    Slang is usually language only young people would use. Have you heard an adult talk about someone "crushing it"?

    Solution
    • They are crushing it! is informal language because it is slang.
    • I'm, we're, and how's are informal language because they are contractions.
    • Hey! is informal language because it is informal vocabulary.
    • Ki-ki Wala Wala is informal language because it is a nickname.
  • Distinguish what is formal or informal language.

    Formal language does not use overly casual or friendly expressions.

    Formal language does not use slang.
