As a comparison, my German (as a foreign language) used to tell us the first year we learned it, "beginners shouldn't use a bilingual dictionary".

In order to ensure the word you found in the dictionary is correct, you need to be good enough in the language. Often there will be homonymns in your native language, and you'll get the wrong word. For example you want to translate the bank of a river but end up with the place that keeps your money.

It's the same with answers you get from Google or Stack Overflow about programming. If you're not good enough to ensure they're correct, you'll be in trouble.
