Another example: waving sideways with the hand raised in front of the interlocutor in kinetic signs generally means a form of greeting or saying goodbye from a distance, and in the deaf community, performed with both hands, is equivalent to applause (applause) if intended for the deaf.
Finally, the sign of turning your back (or more often turning your head), which in kinetic signs is equated with anger or insult, in the deaf community means that the deaf person does not want to continue listening to the interlocutor, he wants to interrupt the conversation. on a certain topic.
For several decades, in many countries of the world, including Poland, sign signs are also used as an illustration of a verbal expression, regardless of classical sign language. This creates a glaring variety of the spoken mother tongue, known as sign language. The signs of the signs are used in the grammatical order of the native language by adding inflectional endings using the alphabet of the fingers.
Sign language is always used in conjunction with spoken language. This is called language and sign system. This artificially created variety of language, which combines the characteristics of sign language and the national language, is used in teaching deaf children, in television interpretation, as well as in communication with bilingual deaf children, that is, those who have well mastering the Polish language and the simultaneous illustration of verbal expression with signs of sign language facilitate their reading from the mouth.
