When someone expresses an opinion, make sure to actively listen and understand their point of view. This will allow you to respond genuinely and contribute to the conversation more effectively.

4. Use body language

Aside from verbal expressions, using supportive body language like nodding, maintaining eye contact, or using affirming gestures strengthens the impact of your agreement.


Being able to express your agreement effectively is an essential skill in both formal and informal situations.
