Putri

I know this is an Indonesian name, but it is one letter off of you know what.

I have that name. And I was picked on as a kid for having that name. I wasn't very proud of it. But as I grew, I became more and more accepting and now I'm very proud of it.

This was the last name of my sisters. My big sister uses 'Rizka Ayuditha Putri' and my lil sister uses 'Rona Andini Putri'. I think it's pretty.

Putri has a beautiful meaning, but looks too similar to the English word putrid to be usable.

Only in your opinion. The only time I began thinking of it that way was when you mentioned it.
It's true that people can get picked on for it (I also just realised that the pronunciation, when poorly executed, can sound awful), but when pronounced properly, it can really be beautiful. I know someone who's called this (though she goes by another name - by preference, because she prefers to acknowledge her ethnic rather than national roots) and she's a beautiful enough person at heart to merit this name.
