デキる人は「言い回し」が凄い 角川oneテーマ21

Doesn't Do What It Say It Does

For a book about 言い回し it doesn't not talk about 言い回し all that much. This book is more about idioms, common turns of phrases, and "correct" business Japanese.

I think it's useful for Japanese learners working on N1 and above level Japanese who want to improve their understanding of keigo and idols, but it's not so useful if you're after a book that teaches you different words to use in different situations.
