That's right. But you don't necessarily need to know what a word means (its exact meaning) in order to understand a sentence. You only have to feel what it means. For example, for a long time I didn't bother to look up the exact meaning of words like 'ruminate', 'agitated', 'incredulity', 'ilk', 'perpetual', 'stagnant' and dozens of other words. I could feel what they meant, and that was enough. Just like when a 4-year old knows what 'tomorrow' means without understanding the complexities of life and time. He doesn't need to know about Earth orbiting around the Sun; tomorrow means 'sleep once, and when you wake up, that's tomorrow'. I think you can learn a new language just like children learn their mother tongue.
