Keep it specific, behavior-focused, and constructive. Avoid “you always talk over people”; describe what you’ve observed and the impact.
A good structure is:
Observation → impact → request
For example:
“I’ve noticed that you sometimes jump in while other people are still speaking. It can make it difficult for people to finish their thoughts, and we may miss useful input. I’d like you to give people a little more space to finish before responding.”
If you want it warmer:
“You bring a lot of energy and ideas to discussions, which I appreciate. One thing to work on is letting people finish their thoughts before jumping in. It would help make the conversation more balanced and give everyone a chance to contribute.”
If this is formal performance feedback, I’d use the second approach: acknowledge the strength, then clearly name the behavior and expectation.
