The Origin of Coworker or Colleague

The word colleague comes from Latin collega, meaning “partner in office.” It was used to describe people sharing official duties. Over time, English adopted it for professional and academic relationships.

Coworker is a newer word. It combines co- (together) and worker. It became popular in modern workplaces as offices and companies grew larger and more casual.

There is no spelling difference in colleague, but coworker sometimes appears as co-worker. This variation exists because English often drops hyphens over time.
