What Is Sign Language?

Sign language is a visual mode of communication that uses its own grammar similar to spoken language, encompassing hand gestures, body language, facial expressions, and eye gazes.
It is a crucial means of communication for many deaf or hard-of-hearing individuals and those who can listen but cannot speak.
Did you know sign language varies across regions and has distinct dialects similar to spoken ones?
Just like spoken languages, sign language also boasts of regional variations and unique dialects. For instance, American Sign Language (ASL) differs significantly in syntax and vocabulary from British or Japanese sign language, highlighting the rich diversity within the deaf community.
Why the International Day of Sign Language Matters
The International Day of Sign Language plays a critical role in promoting the rights of deaf individuals worldwide. This day emphasizes early access to sign language, which is indispensable for individual development and pursuing international development goals. It highlights the preservation of sign languages as crucial cultural and linguistic diversity components.
It also serves broader purposes, such as effective communication during disasters and helping babies develop early speech.
Supporting this day is a direct nod of solidarity to the deaf community, thereby advocating for an inclusive society.
Data and Statistics

The World Federation of the Deaf states that approximately 70 million deaf individuals worldwide use over 200 different sign languages to communicate.
As of August 2023, 77 countries recognize sign language as an official language or in some form of legislation.
WFD also mentioned only 1 to 2% of the global deaf community has access to education in sign language.
How to Learn Sign Language
Even if you are not deaf, preserve and promote this language by learning it. Here are a few ways to do it:
- Enroll in a sign language class to learn structured lessons and have the opportunity to practice with other sign language users.
- Take online courses and use apps. Websites like Coursera and Lifeprint and apps like SignSchool and ASL App provide interactive lessons and quizzes to reinforce learning.
- Read books and watch DVDs, often including diagrams and videos demonstrating correct hand shapes and movements.
- Practice with a friend or family member to make the process more enjoyable and provide opportunities to correct mistakes and give feedback.
- Find local sign-language meetups on websites like Meetup.com, which provide a supportive environment for learners of all levels.
