what is unsual about the dictionary syme is workin on?

Syme is working on the eleventh edition of the definitive Newspeak dictionary. Syme is very excited because he is destroying hundreds of words every day, "We're destroying words -- scores of them, hundreds of them, every day. We're cutting the language down to the bone." He is excited at the prospect of even less self-expression. Winston feels that he is much too excited for his own good.
