A cohort was originally one of the ten divisions of a legion in the Roman army, containing from 300 to 600 men. The most common use of cohort today is in the sense “group” or “company”: A cohort of hangers-on followed the singer down the corridor. In a development emphasizing the idea of companionship, cohort has also come to mean a single companion, associate, or the like: The senator strode into the room followed by his faithful cohort, his son-in-law.
