I like it when it’s pronounced JAY-ah. It sounds better in my opinion. But either way, I love the meaning, Jaya is a nice name. Not trendy, not too common, overall just nice.
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.
