What is the difference between formal and informal language?
Formal and informal language serve different purposes. The tone, the choice of words and the way the words are put together vary between the two styles. Formal language is less personal than informal language. It is used when writing for professional or academic purposes like university assignments. Formal language does not use colloquialisms, contractions or first person pronouns such as ‘I’ or ‘We’.
Informal language is more casual and spontaneous.
