There are two different uses:
The one-word form, awhile, is an adverb. It modifies a verb such as stay awhile, rest awhile, or sit awhile. It cannot be used as the object of a preposition, such as for.
The two-word form is a while, where while is a noun, meaning an unspecified period of time. So you could similarly say stay for a while, or that you will be gone for a while. So the distinction is that you use awhile with verbs and "a while" in prepositional phrases.
