Morphology

sea + line

The meaning 'the apparent line on the horizon where the surface of the sea seems to meet the sky' is directly and compositionally derived from 'sea' (a body of water) and 'line' (a dividing or marking line). This follows a transparent noun+noun compound logic that a B1 learner who knows both words can readily infer, even if the exact collocation is not very frequent.

Etymology

Sea line comes from the clear visual 'line' where the sea seems to meet the sky. Sailors and travellers watched that visible line as the horizon, so the phrase now means the apparent meeting point of sea and sky.
