Are body language and tone more important than words when communicating?

I'd say body language and tone often carry more weight than the actual words, especially in face-to-face communication. The reason is that they reveal emotions and intentions that words alone might not convey. For example, in my work as a UI designer, when presenting a new design to clients, even if I explain everything clearly, a hesitant tone or lack of eye contact can make them doubt my confidence in the project. On the other hand, a warm tone and open posture can make even critical feedback feel constructive. So while words matter, how we deliver them shapes how they're received.
