Morphology

spar + buoy

The compound is a straightforward noun+noun construction where 'spar' describes the type or shape of 'buoy' — i.e. a buoy resembling or made from a spar (a long, vertical pole). This compositional pattern is common and predictable cross-linguistically, so a B1 learner who knows both constituents should be able to infer the meaning.

Etymology

Spar buoy comes from the words spar, a long wooden pole, and buoy, a floating marker. The literal picture is a tall pole floating upright like a vertical log, so a spar buoy is a buoy that 'marks' a place or hazard at sea.
