Review for The Free Dictionary Search by m
Rated 5 out of 5 stars
I love this dictionary. I find it more useful than webster's and dictionary.com because it lists more medical and science terminology. It also lists the 25 words that come alphabetically before and after your target word, for those times when you can think of part of the word but not the exact phrasing.
