Chron comes from the Greek word chronos, meaning time. Once a learner recognizes this root, words like chronology, chronic, and synchronize become easier to decode, because each one carries some idea of time, order, or timing. Spotting the root also helps with related roots like tele, bio, and graph when they combine with chron, as in chronograph.
