Introduction of Sign Language
Sign language, also known as signed languages, convey meaning visually and manually instead of through spoken words. They are full-fledged natural languages with their own grammar and lexicon, expressed through manual articulation and non-manual markers. Although sign languages are not universal and are usually not mutually intelligible, there are similarities among different sign languages.
Linguists consider both spoken and signed communication to be types of natural language, evolving over time without meticulous planning. Despite differences in modality, there is substantial overlap between the neural substrates of sign and spoken language processing. It’s important to note that sign language should not be confused with body language, which is a different form of nonverbal communication.
Sign languages have developed wherever communities of deaf people exist and are integral to local deaf cultures. While the deaf and hard of hearing primarily use signing, hearing individuals also utilize it if they are unable to speak, have difficulty with oral language due to a disability or condition, or have deaf family members.
The number of sign languages worldwide is uncertain, with each country typically having its own native sign language. Some countries have multiple sign languages. Indo-Pakistani Sign Language is currently the most widely used sign language globally. Several sign languages have received legal recognition.
Linguists differentiate natural sign languages from other systems, such as constructed manual codes for spoken languages, home sign, “baby sign,” and signs learned by non-human primates.
History
The earliest written records of a sign language date back to the fifth century B.C., as evidenced by Plato’s Cratylus, where Socrates acknowledges the potential for using hand and body movements for communication. Until the 19th century, people primarily limited their knowledge of historical sign languages to manual alphabets designed to facilitate translation from spoken to sign language, rather than documenting the languages themselves. Debate regarding the monastic sign-language of the Middle Ages now regards it as a gestural system rather than a true sign language.
Contact between Europeans and Indigenous peoples in the Gulf Coast region revealed a fully developed sign language by the time of European arrival, documented by accounts from the 16th century. Spanish monk Pedro Ponce de León developed the first manual alphabet in the 16th century, based on hand gestures used by silent monks. In the 17th century, Juan Pablo Bonet published the first modern treatise on sign language phonetics in Madrid.
In Britain, manual alphabets were utilized for various purposes, including secret communication and communication with deaf individuals. George Dalgarno’s 1680 publication introduced an “arthrological” alphabet for deaf education, while Charles de La Fin’s 1692 book described an alphabetic system based on body parts.
Frenchman Charles-Michel de l’Épée’s manual alphabet, published in the 18th century, remains largely unchanged in France and North America. He founded the first school for deaf children in Paris in 1755. Sign languages typically bear no linguistic relation to the spoken languages of their respective regions, with variations influenced more by geographic location and historical factors than by spoken language dialects. At international deaf events, experts have recognized International Sign as a complex language rather than a simple pidgin.
Conclusion
In conclusion, sign language, with its rich history and diverse forms, plays a vital role in deaf communities worldwide. From its early origins, such as Plato’s mention in the fifth century B.C., to the development of manual alphabets and educational methods by figures like Pedro Ponce de León and Juan Pablo Bonet, sign language has continuously evolved.
Throughout history, various cultures have contributed to the advancement and recognition of sign languages, including the pioneering efforts of individuals like George Dalgarno and Charles-Michel de l’Épée. These efforts culminated in the establishment of institutions like the American School for the Deaf and Gallaudet University, fostering education and empowerment for the deaf community.
Sign languages, despite their complexity and independence from spoken languages, exhibit unique correlations and variations across different regions. For instance, while English-speaking countries predominantly use American Sign Language (ASL) or variants thereof, sign languages in other countries may have different origins and characteristics.
Moreover, the emergence of International Sign, recognized at global deaf events, underscores the need for cross-cultural communication and solidarity among deaf individuals worldwide.
In essence, sign language represents not only a mode of communication but also a vibrant expression of deaf culture and identity. Its ongoing evolution and recognition underscore the importance of fostering inclusivity and accessibility for all individuals, regardless of their hearing abilities.
