Morphology

posse + comitatus

Although the constituent glosses ('group summoned' and 'armed retinue') hint at groups of people, the compound is a fixed Latin legal term referring specifically to a doctrine limiting military involvement in domestic law enforcement. This technical, historically specific legal meaning is not compositionally derivable from the parts for an average B1 learner, so the expression is opaque.

Etymology

Posse comitatus comes from old Latin where posse meant 'power' and comitatus meant 'county'. Long ago a sheriff could call local men to form a force to catch criminals, so the phrase now means a temporary group that helps the authorities.
