Kinesics

Kinesics is the study and interpretation of nonverbal communication related to the movement of any part of the body or the body as a whole; in layman's terms, it is the study of body language. However, Ray Birdwhistell, who is considered the founder of this area of study, never used the term body language, and did not consider it appropriate. He argued that what can be conveyed with the body does not meet the linguist 's definition of language.

Birdwhistell pointed out that "human gestures differ from those of other animals in that they are polysemic, that they can be interpreted to have many different meanings depending on the communicative context in which they are produced". And, he "resisted the idea that 'body language' could be deciphered in some absolute fashion". He also indicated that "every body movement must be interpreted broadly and in conjunction with every other element in communication".

Despite that, body language is still more widely used than kinesics. Dr. Maziar Mir in his book Body Language of Iran, has defined body language as follows: to all gestures, postures, movements, human behaviour, body gestures, and even model and gesture of speaking, or all postures of making sounds without making a sound that is based on the age, sex, height, weight, and social or geographical status of human beings are referred to as body language or non-verbal communication.
