Do a quick Google search, I was looking for the same thing and found a list but it wasn't every one on it, just the more common I think but I could have been wrong.
I did actually, didn't find anything useful though. I don't need every word, just a lot of them Do you remember the link? Thanks.
Not everyone is great at researching I guess. Pick one... google.com/search?q=list+of+three+letter+words&rls=com.microsoft:*:IE-SearchBox&ie=UTF-8&oe=UTF-8&sourceid=ie7&rlz=1I7SKPB
