Coarse and course sound the same, but they mean very different things.
Coarse is an adjective. It describes something rough, crude, or lacking refinement. You might talk about coarse sand, coarse fabric, or coarse language. Example: The towel felt coarse against my skin.
Course is usually a noun. It can mean a class you take, a path or route, or the direction something moves. Example: He enrolled in a history course. You can also say, The river changed its course after the storm.
A quick memory tip helps: course often relates to movement or study, while coarse describes texture or tone.
- Use coarse for rough surfaces or rude speech.
- Use course for classes, paths, and directions.
If you mean rough, choose coarse. If you mean a class or a route, choose course.
