World English Dictionary
flammable (ˈflæməbəl)
liable to catch fire; readily combustible; inflammable
usage  Flammable and inflammable are interchangeable when used of the properties of materials. Flammable is, however, often preferred for warning labels as there is less likelihood of misunderstanding (inflammable being sometimes taken to mean not flammable). Inflammable is preferred in figurative contexts: this could prove to be an inflammable situation
