Firstly, I was interested in how the author introduced the book and its content. I thought the book would give us more real-life examples, but it's too academic after all. The book is about explaining the meaning of words rather than guiding how to use them.
After some chapters, it likes wasting time reading more because it's all about the history and evolution of words, philosophy, and proposition.
One good point of this book is the diverse vocabulary with many synonyms and the pronunciation of some proper names.
For people who already know the basic knowledge of Math or Science, this book is not a good recommendation from me.
