I love this little 1967 book and use it daily. I don't rely on "spell check" on my computer. In fact, I used the little book to check the spelling of "rely" ! LOL
First word is "aardvark", last word is "zymurgy", my best estimate of the middle word (you don't think I'm bored enough to count them all, do you?) is "itinerant", no definitions, 81 pages at the end of grammar rules and other obscurities.
