congregational

The word 'congregational' traces its lineage to the Latin verb congregare, meaning "to gather together into a flock or assembly." This verb itself is a compound of the prefix con- (together) and gregare (to collect into a flock), derived from grex, gregis (flock, herd). The addition of the noun-forming suffix -ion created congregationem, denoting the act or the body of people assembled. Finally, the adjectival suffix -al was appended, yielding a term that describes anything pertaining to such an assembly. In ecclesiastical history, this logic was specifically applied to local, self-governing church bodies, giving rise to the proper adjective 'Congregational' and the system of church polity known as Congregationalism.
