Course or coarse;

These two words not only have different meanings, but they also have different functions in the sentence. Course can be a noun, where it can refer to several concepts, or a verb, where it means to pulse or flow rapidly. Coarse is an adjective that means rough or loosely arranged. Since coarse and adjective both contain the letter A, it should be easy to reserve this word for uses where it describes a condition of a noun. If you’re using the word as a noun or a verb, choose course instead.
