| Usage notes | Use 'essentially' to summarize or clarify a point. It's neutral and works well in both spoken and written contexts. Avoid in very casual conversations. | Use 'necessarily' to express that something must be true or always happens, but be careful not to use it in overly casual situations, where simpler words might work better. |
