Origin

Early 17th century (denoting the heating of a substance to the point of combustion or chemical change): from medieval Latin ignitio(n-), from the verb ignire 'set on fire' (see ignite).

Ignition initially meant heating something to the point of combustion or chemical change. The Latin ignire ‘set on fire’, from ignis ‘fire’ is also found in igneous rock (mid 17th century) for solidified magma.
