Usage notes[edit]

  • Inflammable, although originally meant as a synonym of flammable, is nowadays often used as an antonym of flammable, and, as such, may be taken to have the opposite meaning to that intended (depending on whether the writer and/or the reader use inflammable as a synonym, or as an antonym, of flammable). Where such confusion might arise, especially where this may be a safety hazard, one may prefer to use flammable or non-flammable (depending on whether inflammable would have been used as a synonym or as an antonym of flammable) or another synonym.
