Hear, listen is an expression used as a short and repetitive form hear him . It represents a listener's deal with the point created by a speaker.
It was originally a necessity to draw attention to the speakers, and has since been used, according to the Oxford English Dictionary, as the "regular form of cheering in the House of Commons", with many goals, depending on the user's intonation. Its use in Parliament is related to the fact that usually (though not always) applause is prohibited in the rooms of the House of Commons and the House of Lords.
That sentence hear him, hear him! used in Parliament since the end of the 17th century, and reduced to hear! or listen, listen! at the end of the 18th century. The verb heard has previously been used in the King James Bible as a command for others to listen.
Another phrase comes from hear, hear , like hear, hear (cheer), to hear (shouting expressions), and < listeners (people who do the same).
The use of exaggerated phrases by a member of the House of Commons Council led by Richard Brinsley Sheridan, in one speech, deviates from his planned text and says, "Where, oh where, we'll find a more ignorant or somebody more stupid than this? ". Members of Parliament who eagerly repeat "hear, hear."
