What is the primary function of gestures in communication?

The primary function of gestures in communication is to show emphasis, transition, and enumeration. Gestures play a key role in enhancing verbal communication by adding emphasis to specific points, indicating transitions between ideas, and helping to enumerate or list information clearly. For example, when someone points to an item while discussing it or counts off points with their fingers, they are using gestures to reinforce their message and make it more engaging and understandable for their audience.

While other options touch on aspects of communication, they do not encapsulate the core purpose of gestures in the same way. Gestures specifically aim to complement spoken language, making ideas more vivid and aiding the audience's comprehension and retention.
