The story of the word

πέλαγος is the water away from land, exactly the water a Greek captain spent his career trying to avoid. Biologists use it for everything that lives suspended in the water column, from plankton to blue whales, as against the creatures on the bottom. The word hides inside archipelago: Italian arcipelago first meant the Aegean itself, the chief sea, and only later transferred to the islands scattered across it.
