Wait Awhile? or Wait For A While?

Awhile and while are different words and are treated differently in their functions. When using awhile (the adverb), omit the preposition: play awhile. When using while (the noun),  add a preposition and separate the “a”: play for a while. You can even separate them without the preposition: play a while, take a while to think, and recognize the noun function. Avoid play for awhile. Got it?
