usage: Although frequently condemned as illogical, the phrases center about and center around have appeared in edited writing for more than a century to express the sense of collecting or gathering as if around a center. The phrase revolve around is often suggested as a substitute; the prepositions at, in, and on are regarded as acceptable with center in this sense: Their objections centered on his lack of experience.
