What aspect does NOT pertain to verbal communication?

Verbal communication is primarily concerned with the use of spoken or written words to convey messages. It encompasses elements that directly involve language, such as vocabulary— the choice of words used; intonation— the rise and fall of the voice when speaking, which can affect meaning; and sentence structure— how words are arranged to create coherent thoughts.

Gestures, however, fall under non-verbal communication. They involve physical movements that can express ideas or emotions without the use of words. While gestures can complement verbal communication by providing emphasis or conveying feelings, they do not pertain to the verbal aspect itself, which is focused exclusively on language and its components.
