Made to move or work at the same time; matched or coordinated with something else; short for 'synchronized.'
From 'synchronize,' which comes from Greek 'synchronos' (happening at the same time), combining 'syn-' (together) and 'chronos' (time). It's a modern abbreviation that became common with computers and digital devices.
We started using 'sync' way before computers—it came from describing perfectly timed actions—but computers made it such a common word that now kids think it's a tech term when it's actually ancient Greek.
