About International Day of Sign Languages:

  • International Day of Sign Languages is celebrated annually across the world on 23 September every year along with International Week of the Deaf.
  • The day supports and protects the linguistic identity of people who are deaf along with other users of sign languages.

The theme of 2021:

  • The 2021 theme, declared by the World Federation of the Deaf, is “We Sign For Human Rights,”.
  • This theme highlights how each of us – deaf and hearing people around the world – can work together hand in hand to promote the recognition of our right to use sign languages in all areas of life.


  • World Federation of the Deaf (WFD), a federation of 135 national associations of deaf people, proposed International Day of Sign Languages.
  • The resolution for the same was adopted by consensus on 19 December 2017.
  • The first International Day of Sign Languages was observed in 2018.
  • The date 23 September was chosen because it marks the establishment of WFD in 1951.

What are sign languages?

  • Sign languages (also known as signed languages) are languages that use the visual-manual modality to convey meaning.
  • Sign languages are expressed through manual articulations in combination with non-manual elements.
  • Sign languages are full-fledged natural languages with their own grammar and lexicon.
  • The United Nations (UN) describes sign languages as full-fledged natural languages, structurally distinct from spoken languages.

Significance of sign language:

  • Sign language protects ‘linguistic identity and cultural diversity’ of all users.
  • Sign language not only plays an important role in educating people, but also is vital in creating employment and vocational training for persons with hearing disabilities.
  • According to the WFD, there are approximately 72 million deaf people worldwide, more than 80 per cent of whom live in developing countries.
  • Collectively, they use more than 300 different sign languages.
