About This Root
From Latin īnsula (island). The metaphor of isolation connects all derivatives: insular (island-like, narrow-minded), insulate (isolate from surroundings, as if making an island), insulation, and insulator. Even insulin is named from the islets of Langerhans in the pancreas. Peninsula means 'almost an island.'
