Of course or off course?
How do you spell it?
The right answer is that when we talk about giving permission to someone or saying ‘yes’ to someone, it’s spelled of course. Of course could also be used to suggest that something is normal or well-known. For example: Of course there are a lot of books, it’s a book fair. When we talk about a ship that is not travelling along the correct route, it’s spelled off course. Off course could also be used about someone being lost or confused. For example: He went a little off course after he lost his job.
