It’s the small words that are important!
One simple reason.
Without them, we can’t understand.
For example, in French, we could say: “J’aime vraiment ta robe”!
Now, the foreigner studying French might have only studied the verbs “aimer” and “robe”. He might not have studied “vraiment”.
In fact, the essential meaning is just “J’aime ta robe”.
So, it’s important to know the typical “vraiment” because then you can parse it out. I mean, you can ignore it. But before you can ignore it, you have to know it.
It’s the small words that are important, and the small words vary depending on which langauge you’re studying.
