To agree or concur; to come to agreement together.
From Old French 'congreer,' combining 'con-' (together) and 'greer' (to agree), with roots in Latin 'gratus' (pleasing, agreeable).
This is an archaic word that means basically the same thing as 'agree,' but it's so old that you'd almost never see it used in modern English—it's the kind of word you find in Shakespeare or medieval texts.
