What is the meaning of approval in hindi?

In Hindi, "approval" has a few meanings depending on the context. For general permission or a sanction, the most common word is 'मंज़ूरी' (Manzoori). Think of getting a loan approved. For a more formal acceptance or agreement, you would use 'स्वीकृति' (Sweekriti). And for a very official endorsement, like from a committee, the word is 'अनुमोदन' (Anumodan). These three words should cover nearly every situation you might need. I found them very useful myself.
