Hi guys 👋 in this blog lets see how deaf and dumb people communicate and how many languages are there in world .

HOW SIGN LANGUAGE WORKS ?
People who are hearing impared communication with the help of gestures energetic movements of the hand accompanied by a lively facial expression like every other language gestures must also be learnt while speaking a person may need a lot of words to say shall we cross the bridge but a single gesture suffices for the deaf. This language is also used that places where listening is not possible underwater by diverse or in space by astronauts. 

People have always wanted to swap ideas with one another in the stone age the topics of discussion probably where how to make fire or how to process the Hides. since humans lived at different places on the earth different languages developed almost simultaneously. Therefore we call bread as bread and the Arabs calls it chubs the Migration of people caused the local languages to make  mix and give rise to new languages today there are more than 6000 languages not including special languages like the sign language for the hearing impaired and many different programming and cipher language. 
Almost 900 million people speak Chinese which is the most widely spoken language of the world Russian at the second place followed by English German with around 100 million people speaking it is at the 10th place many countries such as Germany or Norway generally speak only one language in India hundreds of languages or spoken If a country remains under a foreign influence for too long native languages can die out. In wales which is the part of Great Britain this almost happened because barring a few adults people could speak only English schools and radio programs or now promoting the native language Celtic Welsh. 
Learning a language is always a challenge for example while learning German we find structures such as he is reading a book difficult because this is said in a different way in German sometimes only tricks like a holding the nose help us learn French sounds it becomes very difficult to learn the languages of the people who culture is alien to us assuming or own behavial patterns can lead to confusion and resentment for instance westerns express your refusal by saying no directly in many Asian cultures this is impolite and the refuse communication in and indirect manner that is why learning a language also includes learning the behaviour patterns of the people whose language we are learning.
