flammable
Catches fire readily
Flammable means capable of catching fire easily: flammable materials, highly flammable gas.
The word arose as a clearer alternative to inflammable, which some people misread as meaning "not flammable" due to the in- prefix.
Both words mean the same thing—able to burn.
For safety labels and warnings, flammable is now standard.
