Morphology
The meaning is directly derivable from combining 'underground' (hidden/clandestine) with 'market' (commerce): it denotes a market operating outside official regulation. This adjective+noun composition is cross-linguistically common (e.g., equivalents like 'black market'/'mercado negro') and follows ordinary modification patterns, so a B1 learner who knows both words will likely understand it.
Etymology
Underground market comes from the image of a market held 'underground'—in basements, tunnels or other hidden places—so people could trade without being seen. That's why it now means a hidden or 'illegal' system for buying and selling outside official rules.
