What is Formal and Informal Language?

Formal language is careful, polite language used in serious situations, like in a letter to a headteacher or a school report.
Informal language is relaxed, friendly language used with people you know well, like friends and family.
The way you speak or write can change depending on who you are talking to and the situation.
Choosing the right style is called using the right register (say: REH-jis-ter).
Think of it like clothes: you wear different clothes for a party than for a sports day. Language works the same way.

Features of Informal Language

Uses contractions – short forms like can't, won't, and I'm.
May include slang – very casual words like cool or awesome.
Often uses phrasal verbs – verbs with a small word like put off or give up.
Can have question tags – short questions at the end like 'You're coming, aren't you?'
Uses short sentences and simple words.
Sounds friendly and chatty, like talking to a friend.

Features of Formal Language

Uses full forms – no contractions, so write cannot instead of can't.
Uses precise vocabulary – exact words like assist instead of help.
Often uses the passive voice – for example, 'The cake was baked by Tom' instead of 'Tom baked the cake'.
Uses impersonal constructions – sentences that don't say 'I' or 'you', like 'It is believed that...'
Uses longer, complex sentences with connecting words like however and therefore.
Sounds polite, serious, and respectful.

When to Use Formal or Informal Language

Use informal language with friends, in texts, or in a diary.
Use formal language in school reports, letters to adults, or job applications.
An email to a friend can be informal, but an email to a teacher should be formal.
A speech to the class is usually formal, but a story for fun can be informal.
Always think: Who is reading or listening? That helps you choose the right style.

Rewriting: Changing the Register

You can change a sentence from informal to formal without changing its meaning.
Example: 'I'm sorry I'm late' (informal) becomes 'I apologise for my lateness' (formal).
To make it formal: remove contractions, use bigger words, and make sentences longer.
To make it informal: add contractions, use simple words, and shorten sentences.
Always keep the same meaning – only change the style.

Remember!

Register is the style of language you choose for a situation.
There is a spectrum – not just two boxes. Some language is in between formal and informal.
Using the right register shows you are a good communicator.
Practice by taking a formal sentence and making it informal, or the other way around.

## Formal and Informal Language Language can be **formal** (proper and serious) or **informal** (casual and relaxed). The way we speak or write changes depending on who we are talking to and the situation. This is called **register**. ### Informal Language Use informal language with friends and family, or in texts and casual emails. It feels friendly and relaxed. - **Contractions**: short forms like *can't* (cannot) or *I'm* (I am). - **Slang**: casual words like *cool* or *awesome*. - **Phrasal verbs**: verbs with a small word, like *give up* (stop trying). - **Question tags**: short questions at the end, like *You're coming, right?* - **Short sentences**: quick and simple. ### Formal Language Use formal language in school reports, letters to important people, or speeches. It sounds respectful and serious. - **Full forms**: no contractions, so write *cannot* not *can't*. - **Precise vocabulary**: choose exact words, like *father* instead of *dad*. - **Passive voice**: say *The cake was eaten* instead of *I ate the cake*. - **Impersonal constructions**: avoid saying *I* or *you*; say *It is believed that...*. - **Longer complex sentences**: more detailed and connected. ### Choosing the Right Register Think about your reader and the situation. For a letter to a friend, use informal. For a report to your teacher, use formal. You can rewrite a passage to change its register without changing the meaning. ### Example - **Informal**: *I can't come to your party. I'm too busy.* - **Formal**: *I regret to inform you that I am unable to attend your party due to prior commitments.* Remember: there is a spectrum from very formal to very informal. Choose the right style for the right moment!
