laiane I think I read (a long, long time ago) in The Elements of Style that "flammable" was a word created for the safety of idiots and small children. His words, not mine. Dec 1, 2007
cathari I like to call flame-retardant items "ininflammable". ;) Oct 30, 2007
slumry Flammable and inflmmable both mean combustible. Although "inflammable" is the older, and some say the preferred, word (derived from "inflame,") "flammable" was adopted as the preferred word of caution on trucks, etc. because people began to think that something that was "in-flammable" must be "in-combustible!"
