* Hindi doesn't use last names the same way English does. Hindi names are typically just one or two words, and they are often based on meaning or religious significance.
* Diane is a name of Greek origin. It's not a common name in Hindi-speaking cultures.
What to do instead:
* If you need to introduce someone named Diane: You can say "यह डायन है" (Yeh Diane hai) which means "This is Diane."
* If you want to find a Hindi name with a similar meaning: Diane means "divine" or "goddess." You could look for Hindi names that share these meanings, like "Devika" (divine), "Divya" (divine), or "Devi" (goddess).
Ultimately, the best way to refer to "Diane" in Hindi will depend on the context.
