How to help
Shabdakalpa is more than a dictionary—it is a cultural milestone, a symbol of Bengali’s intellectual maturity, and a once-in-a-generation project to secure its place among the world’s great languages. Historical dictionaries of this kind exist only for a handful of European tongues. For Bengali—the world’s seventh most spoken language—to have one is both urgent and long overdue.
