What form of communication does not rely on verbal expression?

Nonverbal communication is characterized by the transmission of messages or information without the use of spoken or written words. It encompasses body language, gestures, facial expressions, posture, and other forms of physical cues that convey feelings and emotions. This type of communication can often express more than words, allowing individuals to convey nuances of emotion, intention, and interpersonal dynamics without verbalizing their thoughts.

In contrast, written communication involves the use of written symbols or language to convey a message, while oral communication relies on spoken words to express ideas or information. Visual communication, although it may include nonverbal elements, primarily refers to the use of visual aids such as images, videos, and diagrams to communicate information. Therefore, nonverbal communication stands out as the mode that does not require verbal expression at all.
