First of all, what is sign language? For people with serious hearing problems or totally deaf, it is the only visual way of communication. Using their hands and relying on mimics, the hearing impaired people created an appropriate type of language.
In the United States, there are two accepted sign languages: the American Sign Language (ASL) and the English Sign Language (ESL). The latter is based on written English, in which an attribute is placed before the word it determines (for example: blue hat). On the other hand, the ASL is slightly different in terms of the statement structure, topics and grammar (hat blue is the version used by people using ASL). Also, ASL can ignore many connecting words and gestures express whole structures, using much less the fingers to replace letters.
Therefore, there are significant differences in the reception of communication depending on the chosen variant, but also on the area in which it is used. If three fingers on the cheek means gray in Texas, the same sign means black in Florida. However, the beauty of sign language is that you don’t have to be very precise. Facial expressions and gestures render much more than words could ever do. It is like someone telling a story without saying a single word. Another important aspect that differentiates the spoken language from the sign language is that the latter does not have intonation elements. It’s all about facial expression, eyebrow lifting, head inclination, shoulder lifting.
Whatever the situation, knowing the sign language is always useful. Not only does it help you become more expressive, but also guides you in the more accurate deciphering of body language and mimics of others. This way, you become a much better observer. At the same time, sign language is an efficient remote communication method. The only issue is how well you see and are seen. Therefore, it is an excellent way to transmit information in public, without actually saying them out loud, but in silence, as a secret.
