Morphology

mainsail = main + sail (semi-transparent) = main + sail

The compound transparently combines 'main' + 'sail' to indicate the principal sail, but the technical nautical sense (the sail on the mainmast) is specialized and may not be fully deducible by all learners.

Etymology

The word mainsail is made of main (meaning 'chief') and sail, so it names the chief sail on a ship's main mast. That's why a mainsail is the biggest, lowest sail that does most of the work to move the boat.
