Morphology

Atacama + trench

This is a transparent place-name compound: if a learner knows 'Atacama' as a place and 'trench' as a very deep ocean depression, the meaning (a trench located at/near Atacama) is directly inferable. The pattern "PLACE + generic geographic noun" (e.g., Mariana Trench, Peru Trench) is cross-linguistically common and not idiomatic, so no special prior exposure is required beyond knowing the constituents.

Etymology

Atacama Trench gets its name from the nearby Atacama region and the word trench, which means a long, deep 'ditch' or groove. Picture a very deep, narrow 'ditch' under the Pacific Ocean near Chile — that's why the name means a very deep part of the sea floor.
