Communication as a process of sending and receiving messages differs in the multitude of forms in which it appears and is used. That is why, as in many related sciences, there are numerous definitions of communication throughout history. Starting from the basic definition: "Communication is the process of exchanging information through an agreed system of signs, basically the process of sending information to oneself or any other entity, usually through language." the literal meaning of the word communication stands out, which means to share, to make something common, general. Out of ten forms of communication, this paper elaborates on the topic of non-verbal communication. Facial expression, tone of voice, look or body language are just some of the non-verbal signs that we will use and interpret in communication with another person or group. We consider non-verbal behavior by which we express our opinion or attitude about someone or something as non-verbal communication, a way of communicating without the use of words. Intentionally or not, non-verbal communication has the same value as verbal communication, and given that we are often not even aware of it, it is an important subject for learning and behavior of politicians, public figures and all of us. In other words, today perhaps more than ever, non-verbal communication, often referred to as body language, is just as important as verbal communication. Numerous interpretations of communication in general confirm with certainty that a good knowledge of non-verbal signs of communication clearly contributes to understanding the information being transmitted. This paper studys different points of view of what non-verbal communication is, what affects it, and how it, non-verbal communication, affects communication in the general understanding of the message being transmitted. The subject of the importance of knowing non-verbal signs of foreign politicians, more precisely the current president of the Republic of Croatia, Zoran Milanović, the meaning of non-verbal signals as well as their proper use is discussed.
