So when a fuel ignites or combusts, does that fuel itself transform into fire or is fire just created around it?

I know something similar has been asked before but it was different as in just wanting to know what happens to the fuel of a fire and I didn’t exactly find the information I’m looking for.

My question is, I guess, more so asking for specific details about combustion.

Google’s online dictionary basically explained combustion as the process of fire “consuming” it’s fuel.

I was then wondering if this was comparable, even if only in analogy, to fire actually eating the fuel like maybe the matter which said fuel is composed of actually transforms Into fire as it burns rather than only producing fire as it breaks down from burning.

The fuel oxidises and produces heat. The flames you see are usually the products of this oxidation.

Ethanol for example is C2H6O. When it burns it combines with O2 in the atmosphere and makes CO2 and H2O and a lot of heat.

The flames you see are carbon dioxide and water vapor heated up so much that they emit light.
