cald = warm because Romania loves us :Þ
Yes, it's the opposite of what you would expect if you speak English or German :P
In Italian there's the word "caldo" for warm. Is there a latin root? Because in Spanish we have "calido" I really don't know.
Even in French, we can see some link with the word "chaud" even if the pronounciation and the Celtic influence changed the word a lot. I definitely think there is a Latin root.
Calor - latin for heat. Can someone please explain what "a warm and fresh potato is?"
