Question: How did thay make up sign language

Hey!

Official sign languages have existed at least for 400 years and have developed all around the world, but local sign languages probably existed since the beginning of time. Often deaf people would live in small groups or communities, where they developed their own signs to talk to each other and communicate things. In some old cultures both deaf and hearing people would use signs and sign language to communicate with one another. It must have taken some time to develop and understand what the signs mean.

At the beginning sign language was only using hand notions and signs spelling the alphabet to make words to communicate. – On of those alphabets was first used in the British Isles and then taken to the colonies Australia, New Zealand and India, where it was used as well.

Now there is actually an international sign language which can be used by people all over the world to understand one another, no translations required 😉
