Morphology

rocket + fuel

The meaning 'a substance burned to propel a rocket' is directly and compositionally derived from 'rocket' (a rocket vehicle) + 'fuel' (material burned for energy). This noun+noun compound follows a common, transparent formation found across languages, so a B1 learner who knows both constituents will readily understand it.

Etymology

The noun rocket fuel comes from the clear image of a rocket and its fuel, very strong fuel that burns and makes a rocket rise into the sky. So it means the substance burned to give a rocket the power to 'move'.
