I read this in Word by Word by Kory Stamper:
Try it: "this will only take a week" and "this will only take about a week" mean almost the same thing. The pivot point for meaning is not "take" but "about" which means that this use of "take" is a straightforward transitive use.
As we know, "pivot" here means the central or most important. What I want to ask is why the author is considering "about" as the pivot point whereas it should be "take" in my opinion? Because "about" is sort of redundant here. Without it there is no alteration in the meaning of the sentence. Am I right?
