This is a wonderful book of etymology. I don't understand why one person is complaining about abbreviations. If you have an interest at all in etymology, which I assume you do if you bought this book, then you should know F. stands for French, OF stands for Old French, OE, ME, are Old and Middle English, etc. Not hard. I never memorized anything and with no previous training, was quite capable of easily discerning word origins.
And for the guy that couldn't find police roots, what book were you looking in? The entry for police does give an alternate pronunciation, then gives the changes in definition from 16th century to modern times. Then it shows the formation of the word starting with F. back to medL. then to L. politia. Maybe he was confused because it did not show the relation to Greek -polis he seemed to be expecting. While they probably share a root much farther back, this book tends to stop at the Latin or OE root. Because to go any further I suppose you would be talking Indo-European.
I would also like to point out that English does not derive from Latin, that's why it stops at the OE root sometimes. We have borrowed many words from Latin, some which came into our language after the French. If you do not realize this, I suggest you get an introduction to English History. Otherwise, many things in this dictionary will apparently leave you frustrated.
I do not have the other dictionary recommended here. I was given the Oxford one as a Christmas present, and I love it. Certainly, there are not nearly enough words in it for me, but I feel that would be the case regardless. It is well written, and easy to read ,which is a plus as I have terrible eyes. Possibly the other is better, I plan to buy it anyway, because the more the merrier. Also, this ODEE now has a rather smart blue dust jacket, which looks much better than the picture shown here. Without a doubt though, this is the crown jewel of my reference selection.
