Atm I only know English and Spanish (Because of my dad.)
I don't know about in other countries, but in the US you have to take one foreign language to graduate. Mine will be Latin and a year of French because you need 3, but we only have Latin 1+2.
I only speak English :|
When someone "speaks" a language, it means they are fluent, meaning they can hold a conversation with others.
I hope everyone else takes that into consideration ;p
