“Let’s rest for awhile.”
Confusables Entry 403 / 1605 60-second read
Awhile vs. A while
Adverb versus noun phrase.
The comparisoni
“Let’s rest for a while.”
The ruleii
¶
AWHILE after a verb. A WHILE after a preposition.
AWHILE is an adverb meaning "for a short time" — it already has "for" baked in. Use A WHILE (two words) as a noun phrase after prepositions like FOR or AFTER.
Memory aidiii
Remember it like this
After "for," use "a while." After nothing, "awhile."
