WHAT IS SIGN LANGUAGE?
Sign Language is a complete, natural language that uses the visual-manual modality to convey
meaning, rather than spoken words. It is expressed through manual articulation, utilizing
handshapes, movements, and locations, combined with non-manual markers such as facial
expressions, head movements and tilts, and body postures. Unlike simple gestures, sign
languages are fully developed linguistic systems with their own complex grammar, syntax, and
lexicon that are independent of the spoken languages surrounding them. They are not universal,
and there exist over a hundred of fifty to three hundred distinct sign languages worldwide, all of
which are developed naturally within specific communities, for example, American Sign
Language (ASL) in the United States of America, Indian Sign Language (ISL) in India, Japanese
Sign Language (JSL) in Japan, and British Sign Language (BSL) in the United Kingdom. Sign
languages are not only primarily used by Deaf and hard-of-hearing individuals, but they are also
utilized by hearing people, including family members and interpreters who want to communicate
well with them.
WHY DO WE NEED SIGN LANGUAGE?
Sign language is essential in daily life because it provides full, immediate, effective, and nuanced
communication access for the Deaf and hard-of-hearing community, who are often born to
hearing parents and are surrounded by hearing people who may not speak it. It acts as a critical
tool for social inclusion and allows Deaf and Mute individuals to participate fully in different
spheres of society without relying on interpreters or written notes, which are often slower and
less expressive. Beyond accessibility, sign language also offers significant cognitive and
developmental benefits, like for young children, it supports early language acquisition and allows
efficient expression before their verbal skills develop, and for all general users, it enhances
spatial reasoning, memory, body language interpretation, and expressive skills, while also
enabling communication in noisy environments or situations requiring silence. Sign language is
thus more important than most people realize.
