The Role of Negative Words That Start with O in Conflict Resolution

Negative words that start with O, such as “obnoxious,” “oppressive,” and “overbearing,” can significantly impact conflict resolution. Using these words during a disagreement often heightens tension and makes it harder to reach a peaceful resolution. For example, labeling someone as “obnoxious” or “overbearing” can immediately put them on the defensive, creating barriers to effective communication. These words can shift the focus from resolving the issue to attacking the other person, which only deepens the conflict.
