1. Politely Interrupt: Wait for a natural pause in their speech, and then politely interject with a comment or question relevant to the conversation. This can help change the direction of the discussion and give you an opportunity to speak.

2. Use Body Language: Position your body in a way that signals you are not interested in continuing the conversation. Cross your arms or angle yourself away from the person, and avoid making eye contact.

3. Redirect the Conversation: Steer the discussion towards a topic that you find more engaging or relevant. Ask open-ended questions to guide the person away from what they’re currently talking about.

4. Set Boundaries: If someone is talking too much, politely but firmly let them know that you don’t have time or are not interested in discussing that topic at the moment. Stick to your boundaries and don’t feel compelled to keep engaging with them.

5. Use Humor: Make a light-hearted joke about their tendency to talk a lot, which may lead them to feel self-conscious and encourage them to stop dominating the conversation.

6. Enlist Help from Others: If you’re in a group setting, try involving other people in the conversation to break up the monologue from the annoying individual.

7. Create a Distraction: If possible, come up with an excuse or task that requires immediate attention, allowing you to leave or end the conversation gracefully.

8. Offer Constructive Feedback: If you have an ongoing relationship with this person, provide honest feedback about their habit of talking excessively. Explain how it impacts others and offer suggestions for improvement.

9. Be Direct: Politely tell them that they’ve been dominating the conversation and that it’s important for everyone to have an equal chance to speak.

10. Set a Timer: In formal settings, like meetings or discussions, impose time limits for each person’s contribution, so everyone gets an equal opportunity to share their thoughts.

11. Use Headphones or Earbuds: If you’re in a shared workspace, putting on headphones or earbuds can signal that you’re not available for conversation — even if you’re not listening to anything.

12. Be Patient and Practice Empathy: Sometimes, people talk excessively because they’re anxious or have difficulty reading social cues. Try to be understanding and patient with them while also looking for opportunities to assert your own needs in the conversation.
