Morphology

Peru-Chile + trench

The compound name is transparently built from the place names 'Peru' and 'Chile' plus the noun 'trench' (a deep ocean depression), so a learner who knows the country names and the meaning of 'trench' can infer it denotes a trench off the coasts of Peru and Chile. This compositional place-name + feature pattern is common cross-linguistically and follows regular English naming conventions, making it immediately comprehensible at B1.

Etymology

The Peru-Chile Trench is named for the long, deep trench in the Pacific Ocean off the coasts of Peru and Chile, made where part of the sea floor moves under the land. That's why the name refers to a 'deep underwater valley' near those countries.
