What might syme have used to start a conversation with Winston?

Syme might have initiated a conversation with Winston by discussing the latest developments in Newspeak or the Party's language policies, given their shared interest in linguistics. He could have also brought up recent changes in the Party's Propaganda or the latest edition of the dictionary, using these topics to engage Winston's thoughts on the implications for individual expression and thought. This would provide a natural opening for them to explore deeper themes of control and reality under the Party's regime.
