Surface Forms

Morphology

Mason-Dixon + line

The element 'line' transparently signals a boundary, so a learner who knows the words could infer this is some kind of dividing line; however 'Mason-Dixon' are proper names with no semantic content for most learners, and the specific historical/geographical sense (Maryland vs. Pennsylvania; symbolic North–South divide) is not derivable from the constituents. Because part of the meaning (a boundary) is transparent but the culturally specific referent and symbolism are not, this is best classified as semi-transparent.

Etymology

Mason-Dixon line comes from two men, Mason and Dixon, who measured and marked the border between colonies in the 1760s. Because that border later showed a clear split between 'North' and 'South', people now use Mason-Dixon line to mean a symbolic 'dividing line' between different regions or ways of life.
