English is the only major language (that I know) that doesn't have gender specific nouns!
I mean
German, Italian, French, Spanish, Portuguese, all Slavic languages (Russian, Czech, Croatian, Polish....) have them, but not English. Maybe this is why compared to other languages English has so many unisex names?
Will have to look into it more!
I know I have a hard time with some word-names you find unisex.
