cen·ter (sěn'tər) n.
v. tr.
[Middle English centre, from Old French, from Latin centrum, from Greek kentron, center of a circle, from kentein, to prick; see kent- in Indo-European roots.] Synonyms: These nouns refer to a region, person, or thing around which some activity is concentrated: a great cultural center; the focus of research efforts; the headquarters of a multinational corporation; a town that is the heart of the colony; the hub of a steel empire; the seat of government. Usage Note: Traditionally, the verb center may be freely used with the prepositions on, upon, in, or at; but some language critics have denounced its use with around as illogical or physically impossible. But the fact that writers persist in using this phrase in sentences such as The discussion centered around the need for curriculum reform, a sentence that 71 percent of the Usage Panel accepts, suggests that many people perceive center around to best represent the true nature of what they are trying to say. Indeed, in an example like A storm of controversy centered around the king, the only appropriate choice seems to be around. Still, if one wishes to avoid the phrase center around, the phrase revolve around is available as an option. Since center can represent various relations involving having, finding, or turning about a center, the choice of a preposition depends on what is intended. There is ample evidence for usages with each preposition listed above. The Panel accepts all of these uses except the one with at. Seventy-seven percent reject the sentence The company has been centered at Atlanta for the last five years. See Usage Note at equal. |
