A110, you also asked at,
I think that the book you want to accomplish such a prodigious undertaking is,
The Longman Language Activator
I don't know if you read the material I copied at that link.
The great thing about this dictionary is that it isn't really a dictionary in the normal sense of the word.
It takes English words, not the concrete ones like table, chair, window etc, but the more abstract ones, the idioms, the everyday language words, the oness that are difficult to grasp, and centers them around keywords, simple keywords, most or many of which you probably already know.
like falling off a log
If you don't know the meaning you, as in a normal dictionary, look it up. The keyword is EASY. You go to EASY and there you find two [I think] sections,
EASY and EXTREMELY EASY
The grand thing about this book is that virtually all the words and phrases that there are in English that have that meaning are found here, along with good explanations, whether it's BrE or AmE, degree of formality, and excellent corpus based examples.
This is something that a thesaurus doesn't do. That's why this is called an Activator, because it allows you to begin using these new words and phrases in a native speaker fashion.
Again, it's thee
best book for increasing both active and passive vocabulary.
Instead of taking a lifetime to be exposed to all the uses of EASY, you're exposed to them all at once.
