Words are Hamlet's constant companions, his weapons, and his defenses. ...And yet, words also serve as Hamlet's prison. He analyzes and examines every nuance of his situation until he has exhausted every angle. They cause him to be indecisive. He dallies in his own wit, intoxicated by the mix of words he can concoct; he frustrates his own burning desire to be more like his father, the Hyperion. When he says that Claudius is "... no more like my father than I to Hercules" he recognizes his enslavement to words, his inability to thrust home his sword of truth. No mythic character is Hamlet. He is stuck, unable to avenge his father's death because words control him.
