"good girl"

Translation: dobrá holka

[xuan.hua1]

Can I say " hezká holka " ?

[kacenka9]

Nope. not for 'good girl' You could say "hodná holka" as in well behaved girl. Hezká is pretty

[xuan.hua1]

but "hezký víkend" means nice weekend, so can I read "hezká holka" as nice girl?

[kacenka9]

The problem is that in English "nice" means "hezký" only when referring to things. When you talk about people it is a desciption of their inner beauty. While "hezká" is external look. Nice girl in Czech would be Milá or příjemná holka.

What's the difference between holka and děvče? Are they interchangeable?

[sailorsgonnasail]

Could this phrase be used when addressing a pet? Or is it strictly meant for humans?
