[Middle English centre, from Old French, from Latin centrum, from Greek kentron, center of a circle, from kentein, to prick; see kent- in the Appendix of Indo-European roots.] Usage Note: As a verb center can represent various relations involving having, finding, or turning about a center. The choice of a preposition to accompany center depends on the meaning one wants to convey. For certain physical uses, the Usage Panel favors in more than at. In our 1996 ballot, 73 percent found in acceptable, but only 23 percent accepted at in the sentence The company has been centered (in/at) Atlanta for the last five years. · In figurative contexts, there is ample evidence for center in, on, upon, and around. In our 2006 survey, for example, 91 percent of the Panel accepted center on in the sentence The discussion centered on the need for curriculum reform. Some language critics have denounced center around as illogical—if something is in the center, after all, it cannot be "around" something else. Nonetheless, 71 percent of the Usage Panel accepted center around in the 1996 survey, suggesting that, logical or not, center around must be considered a standard idiom. But if the expression does not seem a comfortable fit, revolve around offers itself as a substitute that clearly evokes an orbiting body. See Usage Note at equal.
