What does Syme work on?

"Syme works on the systematic destruction of language. He is working on the 'The Eleventh Edition / the definitive edition of the Newspeak Dictionary. Syme loves his work,”‘It’s a beautiful thing, the destruction of words." Syme's zeal and zest are readily apparent to Winston. Winston looks at Syme and thinks that he is a "dead man". Although the party likes efficiency, they hate personal/individual satisfaction. Syme's zeal for his job will inevitably get him "unpersoned" (killed)."
