原文: This is among my favorite names. As was said above, it means victory in Sanskrit. Most Indians would pronounce it like JAH-yah, but that might be difficult for an anglophone, in which case I would recommend the equally gorgeous pronunciation of JIE-yah. It's hard to believe that this name isn't hideously popular, I mean, it has a fantastic sound, meaning, and look. Whatever. I'm happy that it's remained in relative obscurity.
原文: I have two different friends who are both named this and one of them said her name was a variation of Gaia, which is the earth in Greek mythology (I think) and the other said that she was named after Mt. Jayapura in New Guinea.
