Morphology

demarcation + line

The meaning is directly compositional: 'demarcation' (the act of marking boundaries) combined with 'line' (a boundary or division) yields 'a boundary that marks limits.' This noun+noun construction is common across languages and follows transparent compounding, so a B1 learner who knows both constituents can readily infer the MWE meaning.

Etymology

Demarcation line comes from the simple picture of drawing a clear line or demarcation on a map or on the ground to show where one area ends and another begins. That's why today demarcation line means an agreed 'boundary' that marks the limits of a place.
