Word Root of GREGARIOUS
The Latin word grex, meaning “flock,”and its form gregis give us the root greg. Words from the Latin grex have something to do with flocks or groups. Anyone gregarious, or social, enjoys being part of the flock. To congregate is to gather as a flock or crowd. To segregate is to separate away from others or away from the flock.
