write, and paraverbal communication, which is the way they use their voice. Gestures and facial expressions
are key elements of nonverbal communication as they can convey information about people's emotions,
intentions and expectations, leading to deeper and more satisfying relationships, both in the personal and
professional context. Nonverbal communication is generally defined as the aspect of communication that is not
expressed in words. Abercrombie [12] claimed that we speak with the vocal organs, but we converse with the
whole body. Starting from the assumption that "one cannot not communicate" [13], and that all movements are
to some extent expressive, all nonverbal behaviours are summarized in this definition, which also suggests that
nonverbal communication includes a wide range of behaviours, some of which may not even be considered as
such. Therefore, in addition to more obvious nonverbal behaviours such as facial, vocal and postural
expressions, touch, proxemics and gaze, we can also list physical attraction, facial morphology, as well as
behavioural choices such as hairstyle, clothing or more generally one's external appearance. Some researchers
have also included material objects, which perform communicative functions within a given society [14].
Therefore, nonverbal communication is the process of conveying meaning without the use of written or spoken
words. Also said, any communication made between two or more people using facial expressions, hand
movements, body language, postures and gestures is called nonverbal communication. In the field of
communication sciences, nonverbal communication is divided into four components: the paralinguistic system
indicates the set of sounds emitted in verbal communication, regardless of the meaning of the words, and is
characterized by tone, frequency, rhythm and silence; the kinesic system includes all communicative acts
expressed by body movements such as eye contact, facial expressions, gestures, posture; the proxemics
analyses the messages sent by occupying space that tends to be divided into four main zones: intimate zone,
personal zone, social zone and public area; the haptics consists of communicative messages expressed through
physical contact. In this case we also move from codified forms of communication (a handshake, a kiss on the
cheek as a greeting to friends and relatives), to others of a more spontaneous nature (a hug, a pat on the
shoulder), [15]. Nonverbal communication may act as reinforcement, substitution, contradiction, accentuation,
regulation. It often happens that individuals believe they have sent a clear message when, in reality, this is not
the case. Humans overestimate both the intensity of their expressions and the clarity, that is, the ease with
which their expressions can be interpreted, as well as the extent to which they are observed by others [16].
Often referred to as body language, nonverbal communication can take many forms and be interpreted in
multiple ways by different people, especially across cultures. Even the lack of such nonverbal cues can be
significant and, in itself, a form of communication. Each movement and combination of body movements, such
as changes in posture, eye direction, gestures, and facial expressions, provide signals that are often
unambiguous and sometimes contradictory, meaning that one person may convey one piece of information
while their body language conveys a completely different message. One reason nonverbal communication is so
informative is because people use so many different aspects of their behaviour, appearance, and environment to
convey meaning. These types of nonverbal communication can vary greatly across cultures because each
culture interprets posture, gestures, eye contact, facial expressions, vocal noises, use of space, and time
differently [17].
Knowing, studying and being able to decipher these non-verbal messages can be a concrete help in making the
verbal communication more effective, meaningful and complete as well as respectful of the cultural differences
inevitably present in all the daily relationships [18].
LANGUAGE LEARNING AND NONVERBAL COMMUNICATION
The integration of language and culture should be considered as one of the fundamental purposes of language
teaching and learning and a key element to promote intellectual opening and curiosity, respect for cultural
differences, and the enjoyment in interaction with people from other countries. Consequently, it becomes
necessary to integrate the linguistic code with all the other dimensions that are involved in that linguistic
context. Communication between speakers of different languages is also about understanding the perceptions
and meanings arising from the other speaker, according to their cultural context. Language is, in many aspects,
a social factor and it conveys social, cultural and personal messages, and in doing so it is accompanied by a
whole series of important elements that enrich it but also make it much more complex. Sometimes, for those
