record_voice_over Why this helps your speaking
In conversation, the speaker who reaches for the right noun instantly — "issue" not "problem with", "opportunity" not "chance to do something" — sounds natural and prepared. Vocabulary is not about knowing every word. It is about having the right words immediately available. Build this list slowly but actively: use one new noun from each category in every practice session.
