If you enjoy words and appreciate the richness of the English language, then this is a great reference book to keep at hand either to look up the derivation of some specific word or phrase or simply to dip into and browse. My wife and I use it frequently to find out the origins of words, terms, items or sayings we use or come across in the newspaper or books, and it generally has everything, with a brief but clear explanation of origin and how it came to have the current meaning. We use it and enjoy it more than we had imagined we would when we bought it and recommend it pretty much without reservation (other than wishing it was even larger and even more detailed!). It's certainly worth the price.
