The forms of communication are very varied and diverse among themselves, existing forms for each type of need. In this sense, gestures are some of the simplest and most basic forms of communication, although sometimes they can also be very complex due to all that they implicitly imply. Unlike what happens with oral or written communication, gestures are expressive forms that do not include the use of words but are based on movements, facial expressions, forms of body contact, etc. All gestures always want to say something, even those that seem to be done unconsciously or involuntarily. The interesting thing about gestures, which is not the case with words, is that depending on the situation, the culture or the region, the meanings can be highly variable and sometimes even incomprehensible to everyone.
When we talk about gestures we are talking about relatively silent forms of communication (we say relatively because some of them may include clicks or guttural sounds) that do not use common spoken or written language but are established around the common acceptance of what a gesture supposes and of the situations in which it is used. Each region, culture or community establishes its own gestures or body forms of expression and while for the West a kiss may be something innocent and common, for many other cultures it can mean disrespect or even aggression.
The gestures can be performed with the hands, for example the thumb up, making circular movements with the hands, the extended middle finger, the fingers pointed together, etc. They can also be done with the different facial features, for example, biting the lower lip, raising the eyebrows, rolling the eyes, smiling, etc. Finally, they can also be done with the body, for example, moving the arms indicating direction, kicking the ground, breathing deeply, sighing, etc.
