A register, in linguistics, is the way people use different words, spelling or grammar—talk or write differently—to different people, in different situations. They might be more polite to strangers, for example. Or they will be more respectful to their boss at work.
|Very formal||← FORMAL||Normal||INFORMAL →||Very informal|
This chart shows the words or phrases that one would use depending on different registers:
|Very informal||"Ey!" or "Yo!" or "Wassup!"|
|Informal||"Hey!" or "Hi!"|
|Very formal||"Good morning/afternoon/evening!"|
