means A designated, charted route across the sea along which commercial vessels are expected to travel, used to keep ship traffic organized and collisions rare.

from Straightforward compound rather than a buried myth: 'shipping' (from Old English/Old Norse 'scip,' meaning ship, extended to mean the business of moving goods by vessel) plus 'lane,' an old word for a narrow passage or track, originally a country road between hedges. As sea trade grew dense enough to need traffic rules, 'lane' was borrowed from roads and footpaths onto open water — the same logic that later gave us 'air lanes' for planes. The term solidified alongside formal traffic-separation schemes set up by maritime authorities in the 20th century to stop ships from playing chicken in fog.
