What does it mean to beleaguer someone?

To beleaguer someone means to annoy or harass them persistently. The term originates from a military context, where it referenced surrounding or besieging a place. In a more modern context, it conveys the idea of someone being repeatedly troubled or plagued by issues or annoyances, much like a person under siege. This persistent annoyance can take various forms, including continued questioning, criticism, or any form of troubling interaction that makes it difficult for the person to function without distraction or distress.
