Morphology

boundary + line

The meaning is directly and transparently derived from combining 'boundary' (a limit or edge) with 'line' (a mark or division); together they plainly denote a line marking a limit. This compositional pattern is cross-linguistically common and follows straightforward English noun–noun modification, so a B1 learner who knows both words will readily understand it.

Etymology

Boundary line is a picture of a marked boundary or line on the ground, like a fence or a painted mark made by surveyors to separate two areas. That's why it means the place that shows the 'limit' or 'edge' between two properties.
