Formal vs informal register

Register is the level of formality in language, and it should match the audience and purpose of a text. Formal register avoids contractions and slang, uses complete sentences and precise vocabulary — appropriate for essays, job applications, and letters to people you don't know well. Informal register uses contractions, casual expressions and shorter sentences — appropriate for texting a friend or writing a diary entry.
