Question

Is there any difference between flammable and inflammable ?

Answer 1

Flammable and inflammable do not mean the same thing. If something isflammable it means it can be set fire to, such as a piece of wood. However,inflammable means that a substance is capabble of bursting into flames without the need for any ignition. The opposite of both words is non-flammable.

Both of these are synonyms.

Basically, the reason behind this is, we get inflammable from the Latin verb inflammare, which combines flammare ("to catch fire") with a Latin prefix in-, which means "to cause to."

Hence, the antonym for both of these would be nonflammable.
