> 'nerdy' (a word that doesn't even have an equivalent in Russian)

I wonder how many languages actually do have an equivalent. Maybe English is the only one?

When I translate something to Slovak, I also struggle with the word 'nerd'. We do not have a word for this concept. A close one is "bifľoš", which means a person who puts a lot of effort into memorizing school material, but it is implied that the person does not truly understand it. Another one is "kockáč", which means a math-oriented person. But we do not have a word that means: a weird person, because they actually study and understand something.

To me it seems that America is like "no child left behind", while Russia and Eastern Europe are like "if a child gets behind, wolves will eat them, who cares, at least it motivates others to run faster". :D
