Thank you VERY much for that. I ran across a problem with the word "dissolve" last week. The source I'm using now indicates that "solv" is the root, meaning "loosen", and "dis" is the prefix, meaning "opposite". Of course that makes no sense. My Webster's Collegiate Dictionaries at school do not list any but the one meaning for that prefix. Interestingly, my home copy has all six meanings.

Anyway, I recognized a need for an authoritative and thorough list. This certainly fits that bill. Thank you!
