Genoa

From the name of the Italian city of Genoa. "Genoa" comes from "Genua" the name of an ancient city of the Ligurians. Its name is probably Ligurian, meaning "knee" (from Ancient Greek gony "knee"), i.e. "angle", from its geographical position, thus akin to the name of Geneva. Or it could derive from the Celtic root genu-, genawa (pl. genowe), meaning "mouth", i.e., estuary, or from the Latin word of Celtic origin "ianua", meaning "door".
A genoa is also a type of sail, also known as the Genoa jib (named after the city of Genoa).
