Editing While (section)

===Noun===
''A while'' and ''awhile'' are often confused due to the fact that ''while'' is often accompanied by [[Indefinite article|the indefinite article]]. The main difference is that ''a while'' means "an amount of time" or "some duration" whereas ''awhile'' is an [[adverb]] meaning "''for'' some amount of time" or "''for'' some duration".<ref>[http://www.dailywritingtips.com/a-while-vs-awhile/ A While vs Awhile]</ref>

:"I slept for a while before dinner."
:"I slept awhile before dinner."

Both of these sentences yield the same effective meaning. ''Whilst'' is only a conjunction, and so its use here would be incorrect.
