 Both Privy Counsellor and Privy Councillor may be correctly used to refer to a member of the Council . The former , however , is preferred by the Privy Council Office , emphasising English usage of the term Counsellor as " one who gives counsel " , as opposed to " one who is a member of a council " . A Privy Counsellor is traditionally said to be " sworn of " the Council after being received by the sovereign .
