My best friend is called
Bethany but she only answers to
Beth and most of the time I forget that she isn't actually called
Beth. I think it does stand well as a name in it's own right but I prefer
Bethan over
Bethany and
Elizabeth (which I pronounce: eh-LIZ-eh-bəth)
Bethan and
Beth are both on my list as middle name options at the moment. I think
Beth is a no nonsense name, it's not frilly but I think it would lend itself either to tomboy or girly girl well, it also ages well.
