Verbal communication is the most obvious component of the three entities. Part of the reason for this is the fact that words are a part of our daily life. Then again words used in one culture as being seemingly innocent may reflect a most unsavory meaning in another culture. Then too, sometimes the sheer selection of words may be rather poor, or show a disordinant amount of intensity. Words are difficult to choose just depending on their meaning and trying to convey one's viewpoint without needlessly offending the other person is a challenge.
Then there is non-verbal communication which is has been lauded as the the most honest form of communication, but the most difficult to interpret. A person may exhibit the body language of closed posture which may mean that he/she is "closed" to revealing any additional information because of being upset. Or it could mean they are freezing. While we all communicate with our bodies and how they are positioned, we may not know the message we may inadvertently be sending. Non-verbal communication may be a precarious thing when both men and women are engaged in the same discussion. For example, if a clueless male is sending non-verbal signals signal which are being interpreted by a female in close proximity as flirtatious, then that male in question needs to have someone to immediately administer a dose of awareness before this goes any further. I have found it most effective that when I am most uncomfortable with what I perceive an inappropriate message coming from a female I have two choices. First, I can go screaming, running out the room as fast as I can go. (Probably not the best choice.) Or I have the opportunity to do a reality check with my wife, Audrey. Wives, help your husbands out so that they do not get in a no-win situation.
you may partner with them when communication gets tricky.
Sub-verbal communication is the third type. This is a bit of a challenge to adequately convey in written form, because there are some non-verbal sounds that quite frankly I am not sure how to spell. How do you spell clearing your throat? Or clicking your tongue in disgust? What about a breath of air expelled over relief of something? These and a myriad of other sub-verbal vocalizations communicate and influence the message we are sending and what we are feeling. That is why sub-verbal communication can endear someone to you or cause them to want to fight. For instance, "Have a good day!" when said with a cheerful, positive attitude will probably be received very well. On the other hand, "Have a good day!" said with biting sarcasm will offend the intended receiver, even though the words are innocent
One more thought; when communicating with your mate, remember a Greek word, oikodome edify. What you convey, even if you are confronting your mate, should have at its core building the other person up. It is not rocket science. Paul says, "Let us therefore make every effort to do what leads to peace and to mutual edification" (Romans 14;19, N.I.V.).
