History and Development of Sign Language
Sign language is a fascinating form of communication that predates spoken language. Its history can be traced back to the mid-18th century, when Charles-Michel, abbé de l’Epée, developed a system for French words using a manual alphabet and simple signs for expressing concepts. This system eventually evolved into what is known today as French Sign Language (FSL).
French Sign Language served as the foundation for the development of American Sign Language (ASL) and many other national sign languages. Each country typically has its own native sign language, and currently, there are over 200 sign languages used worldwide.
While French Sign Language influenced the development of ASL, it is important to note that ASL has its own unique signs and grammar. American Sign Language is the most widely used sign language in the United States and is recognized as a complete and distinct language.
To visually represent the rich history and development of sign language, here is a table showcasing some of the notable national sign languages:
| Sign Language | Country/Region |
