council (n.)

"assembly of persons for consultation, deliberation or advice," early 12c., originally in the Church sense, "assembly of prelates and theologians to regulate doctrine and discipline," from Anglo-French cuncile, from Old North French concilie (Old French concile, 12c.) "assembly; council meeting; body of counsellors," from Latin concilium "a meeting, a gathering of people," from PIE *kal-yo-, suffixed form of root *kele- (2) "to shout." The notion is of a calling together. The tendency to confuse it in form and meaning with counsel has been consistent since 16c.
