Did you know?

Some words originally used for animals that gather in flocks have been herded into use for people, too. The Latin word grex means “flock,” “herd,” or “group,” and is the root of several English words, including gregarious, which originally meant “tending to live in a flock, herd, or community rather than alone” but has become a synonym for “sociable,” and egregious. The Latin forebear of egregious, egregius, literally meant “out of the herd” but was used figuratively to mean “outstanding in one’s field.” Egregious entered English in the 16th century with that same, now-obsolete meaning, but over time gained a sense meaning “conspicuously bad” or “flagrant,” possibly as a result of ironic use of its original sense.
