Some versions say Odysseus didn't tell the cyclops his name, here is one version.
Odysseus told the cyclops his name was Nobody. He told this to the cyclops named Polyphemus as part of his plan to kill the cyclops who was holding him in the cave, his men. Then, on the morning when Odysseus attacked Polyphemus in his single eye, the cyclops gave a great painful bellow which woke up the neighboring cyclops. They raced to the cave and yelled to Polyphemus "Why did you wake us up so early? How is hurting you?", to which Polyphemus answered "It's Nobody! Nobody is hurting me!"
The other cyclops answered "Well, if nobody is you, then why did you wake us up at this ungodly hour? You should pray to Poseidon, go to sleep, and let the rest of us sleep."
Odysseus was able to kill the cyclops Polyphemus without interference from the other cyclops living nearby due to his trickery of telling the cyclops his name was Nobody. Most versions say however, that Odysseus told Polyphemus his name was nobody, so that when Polyphemus cried out for help, while Odysseus was shoving a stake into his eye, his fellow cyclopes would think that no one was attacking him. But then once Odysseus had escaped Polyphemus and got onto his boat, he cried out 'My name is Odysseus. The great Odysseus has blinded you.' Odysseus probably said this because he was a bit cocky from his victory and he just wanted the cyclops to know who had defeated him. Polyphemus then asked his father Poseidon to curse Odysseus, which Poseidon did do, not allowing Odysseus to reach Ithaca for 10 years.
To trick the cyclopes into telling the others that "nobody" has tricked him.
"NOBDY"
Nobody
1. When the Cyclops Polyphemus asks Odysseus where his ship is, Odysseus lies and says it was destroyed upon the rocks of the shore. 2. Odysseus told the cyclops that his name was "Nobody". When Odysseus and his men blind the cyclops (neither Odysseus nor the Cyclops dies), he yells to his friends for help. They ask him what is wrong and he answers saying, "Nobody's killing me now by fraud and not by force!" (Fagles' translation 9.455). They respond by saying that it must be the plague killing him and they can't help. They advise him to pray.
Bc the Cyclops could tell his father who blinded him.
Odysseus did not tell the cyclops his name cyclops promised him a gift
To trick the cyclopes into telling the others that "nobody" has tricked him.
An example of a paradox in the Odyssey is when Odysseus must tell Polyphemus his name is "Nobody" in order to trick the cyclops. However, when Odysseus finally blinds Polyphemus, the cyclops yells that "Nobody" is hurting him, leading other cyclops to believe that he is unharmed.
Odysseus tells the cyclops that his name is “Nobody”
"NOBDY"
"NOBDY"
When Odysseus is sailing away, he reveals his true name while taunting the cyclops Polyphemus. This proves to be a poor choice that ends up coming back to haunt him later. The name Odysseus originally gives the cyclops is 'Noman' or 'Nobody'.
Nobody
Polyphemus blames his death on "Nobody" and his friends. "Nobody" is what Odysseus tells him his name is. When Polyphemus tells his friend that Nobody is killing him they don't believe him. They take it as no one is killing him. They say Poseidon (their father) has sent the plague to him. His friends tell him to pray to their father!
