ELI5: If fire isn't one of the states of matter (liquid, solid, gas, plasma), then what is it?

Fire is the rapid oxidation of something that is the result of combustion.

A flame (visible part of a fire) may be plasma, however, for most fires we experience it's just the hot gases which are a product of the combustion.
