Synonym discussion
Sense: adverb/1
All four expressions name a short span of time, but they pattern differently. 'Awhile' is a single-word adverb that sits directly after the verb (rest awhile, sit awhile) and never follows a preposition. 'For a while' uses the two-word noun phrase 'a while' after the preposition 'for' and is the everyday choice in spoken English (we waited for a while). 'Briefly' is more formal and usually appears before the main verb (he briefly explained the problem); it focuses on the shortness of the action rather than the rest period. 'Momentarily' in American English also means 'for a moment', though in British English it more often means 'in a moment' (soon), so writers aiming at a global readership prefer 'briefly' or 'for a moment' to avoid the ambiguity.

Etymology
From Old English 'āne hwīle', literally 'a while', where 'hwīl' meant a period of time. By Middle English the two parts were often written together as one word when used adverbially, and modern usage keeps the single-word spelling only for the adverb sense; the noun phrase 'a while' stays separated.
