Origin of flammable

  • From Latin flammāre to set fire to from flamma flame bhel-1 in Indo-European roots

    From American Heritage Dictionary of the English Language, 5th Edition

  • From Latin inflammare ‘to set on fire’ + the suffix -able via English inflammable. The in- prefix is dropped to avoid confusion with non-flammable, as in many English words of Latin origin (but not this word) the prefix "in-" and similar means "not".
