I see this phrase "Let you be" in this paragraph:
The first thing you have to do is to determine what field of words to learn. This means that not all words are worth learning. If you think this step is silly and skip it, you will become so greedy that you want to learn every new word but soon realize the impossibility to do so. As study has shown, for each individual only 2% of 500.000 English words are enough to use in both social contacts and working alone with professional materials. Therefore, your rich vocabulary should only include about 10.000 words relating to your regular uses.
After deciding the field of words you mainly use, you make a plan of learning. Let you be
. . .
According to this, you learn words by understanding how they relate to each other. Hence, it is suitable for beginners. Though this method is easy to follow, it helps only when you want to learn a few words in a short time and remember them for a short time too.
Please explain to me what "Let you be" mean.
I'm expecting for your reply
"Be". It's rather old-fashioned.
