Morphology

Bougainville + trench

The term is a straightforward place-name + geographic feature combination: 'Bougainville' identifies the location and 'trench' denotes a deep ocean depression, so the overall meaning is directly derived from its parts. Naming patterns like place + feature are cross-linguistically common, so a B1 learner who knows both constituents will readily infer the meaning.

Etymology

The place name Bougainville Trench is named after the explorer Bougainville, and trench means a long, very deep 'valley' in the sea floor. So the name helps you picture a very deep part of the Pacific between New Guinea and the Solomon Islands.
