Which of the following is NOT a characteristic of verbal communication?

Verbal communication primarily encompasses the use of words, whether spoken or written. This includes spoken language, written words, and the tone of voice, all of which are critical aspects of how messages are conveyed verbally.

Facial expressions, however, are a part of nonverbal communication. They convey emotions and reactions but do not involve the use of words. This distinction is essential in understanding the scope of verbal communication, which focuses on language as its primary medium for conveying meaning.

The other elements listed—written words, voice tone, and spoken language—all relate directly to how messages are articulated and understood among individuals, making them intrinsic to verbal communication.
