Cohort

Your friend is a crony, confidant, or collaborator, but not a cohort. In ancient Rome, a cohort was a division of three hundred to six hundred soldiers. So careful speakers and writers avoid cohort when referring to one person. Your cohort is not your comrade, ally, teammate, or assistant. It's a whole group, gang, team, posse: A cohort of laborers went on strike.
