The recent discussion on names reminds me of an observation known to old-time APLers: Ravel, the name of the monad , , means the same as unravel.
I wonder if there are other English words having that property? That is, x where x and un-x (or dis-x etc.) mean the same. As far as I am aware, "hevelled" is not an English word, but if it sounds like it should mean the same as "dishevelled". ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
