Yes, they mean the same thing. Inflammable is an older word. They "made" a new word, flammable, to avoid confusion from warning messages on trucks (carrying gasoline, for instance) fearing that people may be confused and think that inflammable meant not flammable. (as the "in" prefix tends to mean) At any rate, they both mean the same things. It's pretty stupid if you ask me :) -Steve -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
