While vs Wile. This is one I didn’t even think of until I came across the wrong one being used. This guy said not to while away the time. Nope. It’s wile, in that case.
While is sometimes considered a conjunction and sometimes an adverbial conjunction. Regardless of what you call it, it means, roughly, “at the same time as.” “Dad did the laundry while the kids brushed their teeth.”
As a noun, wile is defined as “devious or cunning stratagems employed in manipulating or persuading someone to do what one wants.” It’s where the word wiley, as in Coyote, comes from.
In the above example, wile is used as a verb. One does not while away the time, one would wile it away.
(Do you even use wile that much?)
