What is the meaning of "trick" in drama?

The banter role in Shakespeare's plays was often despised by intellectuals at that time, probably because the banter role was equivalent to the clown in modern drama, and its status was very low, which was the lowest in a drama.

In the era when Shakespeare's hierarchy was very clear, people still attached great importance to social hierarchy. In addition, in the drama at that time, the funny characters were often ridiculous, which was incompatible with the elegance and generosity of the intellectual class.

The banter character originated from the ancient fable drama. His antics, songs and dances, and low-level jokes attracted the masses and added entertainment to the drama. In my opinion, the liar in King Lear is not only a liar, but also a symbol of sexual wisdom and justice. His judgment on everything is so thorough and meaningful that I regard him as a "stupid" saint. The role of playing tricks on people plays an important role in King Lear.
