The way we speak...

During the transmitting of the message, two elements will be received: content and context. Content is the actual words or symbols of the message that is known as language, the spoken and written words combined into phrases that make grammatical and semantic sense. We all use and interpret the meanings of words differently, so even simple messages can be misunderstood. And many words have different meanings to confuse the issue even more.
Context is the way the message is delivered and is known as paralanguage it is the nonverbal elements in speech such as the tone of voice, the look in the sender's eyes, body language, hand gestures, and state of emotions (anger, fear, uncertainty, confidence, etc.) that can be detected. Although paralanguage or context often cause messages to be misunderstood as we believe what we see more than what we hear; they are powerful communicators that help us to understand each other. Indeed, we often trust the accuracy of nonverbal behaviors more than verbal behaviors.
Some leaders think they have communicated once they told someone to do something, “I don't know why it did not get done. I told him to do it.” More than likely, he misunderstood the message. A message has not been communicated unless it is understood by the receiver.Communication is an exchange, not just a give, as all parties must participate to complete the information exchange.

Nothing is so simple that it cannot be misunderstood.
