Morphology

rocket + propellant

The meaning is directly derivable from the constituents: 'rocket' (a vehicle) + 'propellant' (a substance that drives or propels). This straightforward noun–noun composition describes a material used to propel rockets and follows common cross-linguistic compounding patterns, so a B1 learner who knows both words would understand it.

Etymology

Rocket propellant is a very literal name: rocket is the flying vehicle and propellant is the thing that 'pushes' it. Imagine fuel burning and sending out hot gas to push the rocket, so the phrase means the material used to make a rocket 'move'.
