As a verb, it means to organize people or things so they work well together. As a noun or adjective, it can refer to items of equal importance, or to numbers that show a position on a map or graph.
From Latin *coordinare* 'to set in order', from *co-* 'together' and *ordinare* 'to arrange', related to *ordo* 'order'. It developed both the sense of equal rank and organized arrangement.
Your body coordinates muscles so you can walk without thinking; organizers coordinate events so they don’t become chaos. In math and maps, coordinates are like addresses that let everything line up in an orderly grid. The hidden idea is always the same: putting pieces into a shared order.
