Morphology

bar + line

The meaning 'a vertical line marking the boundary between bars' is directly and compositionally derived from 'bar' (a musical measure) + 'line' (a mark or stroke). This straightforward noun–noun compound follows common nominal composition patterns and is cross-linguistically transparent, so a B1 learner who knows both words would readily infer the MWE meaning.

Etymology

Bar line: The noun bar line names the thin vertical line in written music that separates one bar from the next. Because it shows the edge of each bar or 'measure', it became the mark that tells musicians where each group of beats begins and ends.
