Preside over is a commonly used phrase that is used to describe the act of leading or managing a meeting or an event. However, there are a number of synonyms that can be used instead of preside over to convey the same meaning. Some of the most commonly used synonyms include chair, conduct, oversee, supervise, regulate, manage and control. Each of these words conveys a slightly different meaning, so it's important to choose the right word based on the context of the situation. Whether you're leading a conference call or facilitating a meeting, using the right synonym can help you project confidence and authority.
