Morphology

fight + fire + with + fire

The phrase literally combines 'fight' + 'fire' + 'with' + 'fire', so a learner can see the idea of using fire as the means to fight fire, which points to the notion of responding with the same force or method. However, this is a metaphorical extension (using 'fire' to mean aggressive methods) and functions idiomatically to mean 'use the opponent's methods against them', so the exact pragmatic sense is not fully predictable without exposure; cross-linguistic parallels help but do not make it fully transparent.

Etymology

The phrase fight fire with fire comes from a simple, literal idea: when a big wildfire is coming, people sometimes burn a small area on purpose so the big fire has nothing to burn. So they literally fight a fire by starting another fire, and the phrase now means 'to use the same harsh method as your opponent'.
