Examples
-

Morphology
Each component contributes directly to the overall meaning: 'quantum' (discrete/quantised) modifies 'field' (a physical region), and 'theory' signals an explanatory framework, so the phrase literally denotes a scientific theory about quantum fields. Although it names a technical discipline, the composition is regular and cross-linguistically transparent, so a B1 learner who knows the three words can infer the general meaning.
Etymology
Quantum field theory comes from picturing an invisible field that fills space (like light or electricity everywhere) and quantum meaning very small, separate pieces. Scientists found particles behave like little ripples or 'bits' of these fields, so the name means a 'theory' that explains particles and fields together.
