Từ điển Oxford Learners Wordfinder Dictionary

constitutional monarchy [constitutional monarchy] BrE NAmE noun
a country that is governed by a king or queen within laws which limit his or her power. Britain is governed in this way, with the Queen (or King) as head of state and with Parliament and the elected government holding almost all the real power. This system began to develop slowly in the 17th century, when the Bill of Rights became law, and then developed more quickly after the Reform Act of 1832.
