The Origin of Sync or Synch
The word comes from synchronize, which means “to happen at the same time” or “to match in timing.”
It comes from the Greek word synchronos, meaning “together in time.”
The short form sync developed as a clipped version of synchronize. In earlier decades, especially in the 20th century, people sometimes wrote it as synch. That spelling tried to match the pronunciation of “synchronize.”
Over time, sync became the standard short form. It is now widely used in technology, media, music, and everyday writing.
Today, sync is the accepted modern spelling. Synch is mostly outdated.
