combustible

Prone to burning

Combustible describes something capable of catching fire and burning: combustible materials, combustible gases.

Storage regulations often distinguish combustible from flammable—both burn, but flammable ignites more easily at lower temperatures.

Figuratively, a combustible situation or temperament is volatile, ready to explode: The political climate was combustible.

As a noun, combustibles are materials that burn.
