Re: Luka as a girl's name
I'm having difficulty imagining a smiling lump of gold! (A lump of gold at which people smile ... yes, perhaps.)
Isn't it likely that English-speaking people assume it's female because it ends in -a? Same as using Andrea for girls? Though there's usually a pronunciation difference there: an DRAY a for males and ANN dree a for females. And Luka would stay the same for both.
