What prepositions are used with center?: Usage Guide

The intransitive verb center is most commonly used with the prepositions in, on, at, and around. At appears to be favored in mathematical contexts; the others are found in a broad range of contexts. Center around, a standard idiom, has often been objected to as illogical. The logic on which the objections are based is irrelevant, since center around is an idiom and idioms have their own logic. Center on is currently more common in edited prose, and revolve around and similar verbs are available if you want to avoid center around.
