Morphology

boundary = bound (transparent) = bound + ary

The noun is formed by adding the adjective/noun-forming suffix '-ary' to 'bound' meaning a limit, producing a word meaning a limit or dividing line.

Etymology

The word boundary comes from the simpler word bound and the ending -ary, where bound means 'limit' or 'edge'. So a boundary is a line or mark that shows the edge between two places.
