Desi is a word that comes from the country of India and it refers to people or things that are associated with the culture of India, Pakistan, and nearby countries. It's like a special word that helps us describe things that are part of this cultural group.
For example, if someone wears traditional clothes from India, we could say that they are dressed in a "desi" style. If we eat food that has spices and flavors commonly used in Indian cuisine, we might call it "desi" food.
It's like a way to group together things that have some common elements, like language, beliefs, practices, and traditions. It's a way to celebrate and share the richness of this culture with others.
