Digital transformation is tied to the broader trend of business transformation and takes ______ to take hold.
b. a while
Which is correct?
Both a while and awhile refer to a vague period of time. However, a while is used as a noun meaning “a period of time,” and awhile is used as an adverb meaning “for a time.”
A good rule of thumb for both: A while is used if it can be replaced with another article and noun like a year or a minute. Awhile is correct if it can be replaced with another adverb such as quietly or shortly.
