According to UNESCO:
“40% of the world’s population does not have access to resources in a language that they speak or understand, which leads to more and more languages being endangered and on the brink of disappearing.”
If we consider some more standard available facts and the UN Universal Declaration of Human Rights, then we have some associated details:
Everyone is entitled to all the rights and freedoms outlined in the Declaration, without distinction of any kind, such as race, colour, sex, language, religion, political or other opinions, national or social origin, property, birth, or another status.
Furthermore, no distinction shall be made based on the political, jurisdictional, or international status of the country or territory to which a person belongs, whether it be independent, trust, non-self-governing, or under any other limitation of sovereignty.
Despite having an estimated 11 million speakers worldwide, most Sylheti speakers consider their language to be a subset of Bengali rather than a distinct language.

At sylhetilanguage.net:
“We promote the campaign for getting a needy official recognition of the Sylheti language in the main origin countries such as Bangladesh and some parts of India along with giving additional approval in some parts of the world also by providing learning resources and materials. “
The tools which we are providing are easy to read and make learning fun. By doing this, we are also raising awareness about the Sylheti language existence and the history of her literary heritage.
We also provide you with a variety of useful information to help you learn and understand the alphabet, words, and other fundamentals of the Sylheti language easily.

Sylheti enthusiasts get to learn more about the Sylheti language as we promote and produce different learning materials.
Whether you speak Sylheti or not, we urge you to come and join our campaign to save our language, which will help us save our heritage and identity for future generations. You can assist us by signing our petition, joining our campaign, supporting us online, sharing our social media posts, informing others about our existence, donating to our campaigns, and producing literature and other educational or campaigning resources.
Kindly help us raise funds because we need them to continue our campaign as a lack of funds does limit what we can do and produce because of the issue of quality.
If a child has access to high-quality resources in Bangla and the few resources in Sylheti are of lower quality, then unfortunately it will ultimately be an easy choice for him/ her just because of poor quality educational material.
If you are an authority, or elected representative of a local or central government, you can help us achieve our goals by working with us. Please do not hesitate to contact us if you require assistance with any good work relating to this introductory or guest lecture/teacher, such as providing downloadable learning materials.
