Etymology

Origin of center

First recorded in 1325–75; variant of Middle English centre, from Latin centrum, from Greek kéntron “needle, spur, pivoting point in drawing a circle,” derivative of kenteîn “to sting”

Explanation

Whether you are the center of attention or hanging out at the recreation center, you are in the middle of it all. You might think of a circle when you think of a center, but a center is also a building or group of buildings. One five-sided place, the Pentagon in the U.S., is actually a center of government activity. A recreation center is a place where a lot of recreation happens, just as a medical center is where a lot of doctors and nurses give medical treatment. These centers are buildings or complexes where a certain kind of activity takes place, and a word before center often tells you what the activity is. As a verb, you can center your attention on something or center a centerpiece in the middle of a table.
