HIN-dee
* HIN: The "H" is aspirated, like the "h" in "hat".
* dee: The "ee" sounds like the "ee" in "see".
It's important to note that the pronunciation of "Hindi" in Hindi itself is slightly different:
हिंदी (hin-dee)
* hin: The "hin" is pronounced with a slightly softer "h" sound, closer to a "h" in "honor".
* dee: The "dee" sound is similar to the English "dee" but with a slightly shorter and more clipped pronunciation.
Ultimately, the best way to learn the correct pronunciation is to listen to native speakers and practice saying it yourself.
