Is Verbal Communication defined as a language as a system for communicating meaning? Nonverbal Communication defined as communicating without words?

In general verbal communication refers to communication
using speech. The verbal communication may be contrasted with written
communication.

Both verbal and written communication make
use of language such as English, Hindi, or Persian. Also, both ways of communicating,
are used to convey meaning, data, information or knowledge. To this extent, it is not
appropriate to define verbal or non-verbal communication on the basis of use of language
or on communication of meaning. However, in verbal communication, it is quite usual to
identify a "non-verbal" component. Used in this sense, non-verbal refers to
communication that is not based on used of words, traditionally considered to be which
form the basis of formal languages. The may include, for example, other ways of
communicating meaning like the tone of speaking, face expressions, and body language.
Lying in between verbal and non-verbal component of verbal communication is
para-linguistics, which refers to sounds like ..oooh, ..aaah, and hmmm... which are
sound people make while speaking, but which are not formally identified words in the
language they speak.

It is important to note that there can
be many other ways of communication used by people which do not fall under the category
of either the verbal, or written communication. For example, the traffic signal lights
and the smoke signals used by native Americans.
