What is the meaning of different in hindi?

The most common word is 'alag' (अलग). You hear it all the time. For example, 'This is different' is 'Yeh alag hai'.

There is another word, 'vibhinn' (विभिन्न). This one is more like 'various' or 'diverse'. So you would use it for 'different types of things'.

But for everyday talking, 'alag' is the one you need. It is the most useful word for a learner, I think. Hope that is helpful for you.
