...can really help you! There are good websites out there, for when you get stuck on a word or concept in Spanish or Russian- but you may not be able to properly navigate them yet.
I recommend a good, old-fashioned dictionary.
Like this one for Spanish: (if you plan to study in Spain)
or this one: (if you plan to stay in Latin America)
For Russian, I'd recommend THIS ONE (as he uses American English)
