Hey friends... looking for a quick once over on this sentence, I'm unsure whether I should use the word "mean" or "means" -- plural or singular:
> These four terms all refer to somewhat overlapping concepts. *As a result, some confusion has surfaced about what each of these terms actually **mean**,* and how they differ from each other
I feel "mean" sounds cleaner, but a friend claims it should be "means". Any thoughts?
