Formal or informal language?
Formal and informal language is also called register. Formal means serious or very polite, while informal means relaxed and friendly. How can you decide if you should use formal or informal language?
Consider your audience!
To help to understand this, compare the following. Imagine sitting in the park and eating a sandwich with your best friend one afternoon. Now compare that to going to a fundraising dinner for a school or a charitable organization with your parents.
In the park, you would most likely feel very relaxed and not worry about what you say and how you say it. Your language would also likely include slang, abbreviations, contractions, and hidden meanings that only the two of you could understand.
At the fundraiser you would probably feel a bit more on edge, especially if there are a lot of people you don’t know very well around you. This would make you more likely to think extra of what you say and do.
As you can see, the language you choose will always be affected by the context and the people around you.
