Why does lord Capulet stop Tybalt?

Answer 1

Because Romeo has a good reputation-- "Verona brags of him to be a virtuous and well-governed youth (I, v, 66-67)." He also says that Tybalt is being immature and behaving stupidly, he is going to cause a riot. He is not behaving properly for a party; he should be happy and having a good time, instead of trying to start a fight. He also tells him to leave Romeo alone because the Prince has declared that there shall be no more fights, and if there are then they will pay with their lives.

Answer 2

The answer depends on what scene you're talking about. For now I'll assume you mean Act II scene V.

Answer 3
