What name does Odysseus first give to polyphemus?

Odysseus first tells Polyphemus that his name is "Nobody." This clever ruse allows him to deceive the Cyclops; when he later blinds Polyphemus, the giant calls for help, claiming that "Nobody" is attacking him, leading other Cyclopes to think he is not in danger. This tactic showcases Odysseus's cunning and resourcefulness.
