Etymology
Origin of synchronize
First recorded in 1615–25; from Greek synchronízein “to be contemporary with”; from sýnchron(os) synchronous + -izein -ize
Explanation
When you synchronize things, you make them happen at the same time. If you have rhythm, you can synchronize your dance moves with the beat of the music. If not, stay off the dance floor. Synchronize, pronounced "SINK-ruh-nize," means "to make things happen at the same time" — even down to a fraction of a second, as in synchronized swimming. In that sport, one movement that doesn't sync, or match up, costs the swimmers points. When you synchronize your wristwatches, people can't blame their watches being fast or slow if they don't come to the meeting spot at the right time.
