gondola: [16] The gondola, the narrow boat used on Venetian canals, gets its name from the way it rocks gently in the water. Italian gondola is an adaptation of gondolà, a word meaning ‘roll, rock’ in the Rhaeto-Romanic dialect of Friuli, in northeastern Italy (Rhaeto-Romanic is a cover term for a group of Romance-language dialects spoken in southern Switzerland, northern Italy, and the Tyrol). Gondola was first applied to the cabin suspended from an airship or balloon in the 1890s (probably as a translation of German gondel).

navy: [14] Latin nāvis ‘ship’ is the ultimate source of navy. In post-classical times it spawned an offspring nāvia ‘fleet’, which passed into English via Old French navie. Other Latin derivatives of nāvis were nāvālis, source of English naval [16], and the verb nāvigāre ‘manage a ship’, from which English gets navigate [16] (navvy [19] originated as a colloquial abbreviation for navigator, a term applied to someone who dug ‘navigation canals’).

In medieval Latin nāvis was applied to the central part of a church, from the passing resemblance in shape to a ship, and the word was anglicized as nave [17]. Nāvis was related to Greek naus ‘ship’, whose contributions to English include nautical [16], nautilus [17], nausea [16] (etymologically ‘seasickness’), and, somewhat surprisingly, noise.
