In AWAD News 33, someone wrote a post saying that the "-aster" of "philosophaster" was a pejorative suffix, and then claimed that the word "newscaster" made sense. To me, this seems like a bit of morphological confusion, because a newscaster is quite literally "one who casts news," while a philosophaster isn't one who "asts philosophs." And the word doesn't morphologically break into "newsc" and "aster." Am I wrong? To me it's like saying the words "dentist" and "desist" are etymologically related simply by the shared "-ist." I don't see much, if any, relation between the two, but I'm willing to hear arguments to the contrary.
