Why We Euphemize
I found the chapter on sex to be the most interesting. I'd go so far as to say that the whole book is worth it for Speaking of Sex and Secretions and Excretions. I learned a huge amount that I never even suspected, having grown up with so many euphemisms as "normal" speech. Even the "proper" terms that I've been taught are usually euphemisms from another language. I also find myself much more accepting of curse words after reading this book.
One aspect of this book that surprised me is that there are sprinkled references to euphemisms in other languages. In retrospect, it is clear that euphemisms often jump from one language to another, and morph slightly as they go from language to language. I found these parts to be fascinating none-the-less, and really makes me wish I had the patience to really learn more than just English.
Bottom line is that I found this book to be delightfully charming. I learned a lot (and have already forgotten far more). As usual, I'll include the escape reasons... If you are bored by puns, have no interest in etymology, or just don't want to think about language now that English class isn't mandatory in your life, I won't think less of you for skipping this one.
