Which aspect is typically not considered part of nonverbal communication?

Nonverbal communication encompasses a variety of ways individuals convey messages without the use of spoken or written words. This includes aspects like body language, facial expressions, and eye contact, all of which are integral to how people express emotions and intentions without verbal cues.

Written letters, on the other hand, are fundamentally a form of verbal communication as they utilize language and text to convey messages. Unlike nonverbal elements, written communication requires the use of words and is considered part of verbal communication, making it distinct from the characteristics typically associated with nonverbal communication. Thus, recognizing that written letters primarily involve the written word helps clarify why this option does not fit within the realm of nonverbal communication.
