    Inflammable and flammable both mean “combustible.” Inflammable is the older by about 200 years. Flammable now has certain technical uses, particularly as a warning on vehicles carrying combustible materials, because of a belief that some might interpret the intensive prefix in- of inflammable as a negative prefix and thus think the word means “noncombustible.” Inflammable is the word more usually used in nontechnical and figurative contexts: The speaker ignited the inflammable emotions of the crowd.
    remember inflammable has in- which means 'into,' meaning it will burst into flame; non- in nonflammable means 'not,' meaning will not burst into flame

      It seems odd, because I think we usually assume the prefix “in…” to negate the meaning of what follows.

      I'm guessing here, but I think that in this case, the “in…” at the start of “inflammable” is not this prefix that we want to assume it is.  I think that “inflammable” is based on the word “inflame” which means to set something on fire.  Something that can be set on fire — something that can be inflamed — would therefore be inflammable.

    Good Question.

    I have read that the word flammable is of relatively recent origin and has replaced inflammable specially in the USA, where people usually think that the Latin prefix in- (used here an intensifier) always means "not".

    It's from the french or latin root words meaning "to set on fire"... ;-)

    Yeah. But, "inflammable" is meant to be used in a figurative sense, while "flammable" is more technical.

    I don't think that there is a difference. They both are hazards to fire.

    Flammable and inflammable both carry the same basic definition. Anything that is flammable and inflammable can react with oxygen and combust. Back in WWII military officials named flammable objects (i.e. fuel tanks as inflammable or fire-proof). Obviously the tank is inflammable, but the fuel is flammable. Inflammable is also a term to ease up the tensity of the word flammable. Most people percieve the word flammable as anything that could easily burn and possibly blow up.

    Yes, they mean the same thing.

    The prefix "in-" usually negates whatever follows. I think this may be the only exception.
