Detailed explanation-1: -Verbal communication is about language, both written and spoken. In general, verbal communication refers to our use of words while nonverbal communication refers to communication that occurs through means other than words, such as body language, gestures, and silence.

Detailed explanation-2: -Symbol-based communication is often used by individuals who are unable to communicate using speech alone and who have not yet developed, or have difficulty developing literacy skills. Symbols offer a visual representation of a word or idea.

Detailed explanation-3: -American Sign Language (ASL) is a complete, natural language that has the same linguistic properties as spoken languages, with grammar that differs from English. ASL is expressed by movements of the hands and face.

As with verbal symbolic communication, the relation between the sign and the signified concept is arbitrary. Unlike verbal symbolic communication, however, nonverbal symbolic communication does not make use of words.
