To coordinate, align, or bring into agreement, especially regarding schedules, information, or understanding.
Shortened from 'synchronize,' which comes from Greek 'syn' (together) and 'chronos' (time). The casual 'sync up' emerged in the 1990s with digital technology, as devices needed to synchronize data, then spread to general business use.
This tech-born phrase has become essential in our hyper-connected world where everything from calendars to expectations needs constant alignment. The 'up' adds a sense of energy and improvement - we're not just matching, we're elevating together to a better state of coordination.
