How is winstons prophecy of symes imminent disappearance ironic?

Answer 1

If you are referring to Winston Smith in Orwell's 1984, Syme had worked with Winston at the Ministry of Truth, but one day, Syme just vanished. The party seems to have "vaporized" him. Winston had observed that Syme was too intelligent, too much of an intellectual, for his own good. The irony of what happened is that Syme was an expert on Newspeak, and caused thousands of words to vanish, but then, he himself became an "unperson" and he was made to vanish.

Answer 2

Winston's prophecy of Syme's imminent disappearance is ironic because Syme is eventually vaporized by the Party for his lack of conformity to their ideology, which is exactly what Winston had predicted. The irony lies in the fact that Winston, who himself is against the Party, unknowingly foresees the fate of someone who shares his rebellious mindset. It highlights the ruthless and unpredictable nature of the Party's control over its citizens.
