Morphology

subway + system

The meaning is directly compositional: 'subway' names the underground railway and 'system' denotes a network or collection, so a learner who knows both words can infer it refers to the city's subway network. This noun–noun combination follows a common cross‑linguistic pattern (e.g. 'metro system') and is therefore immediately understandable to B1 learners.

Etymology

The noun subway system may come from old words that mean 'under' and 'way', with sub meaning 'under' and way meaning 'path'. Early trains ran under city streets, so the image of a path below the road explains why subway system now means the network of underground trains people use to travel in a city.
