Did You Know?

In ancient times, a cohort was a military unit, one of ten divisions in a Roman legion. The term passed into English via French in the 15th century, when it was used in translations and writings about Roman history. Once cohort became established in our language, its meaning was extended, first to refer to any body of troops, then to any group of individuals with something in common, and later to a single companion. Some usage commentators have objected to this last sense because it can be hard to tell whether the plural refers to different individuals or different groups. The companion sense is well established in standard use, however, and its meaning is clear enough in such sentences as her cohorts came along with her to the game.
