Origin: [F. jete a pier, a jetty, a causeway. See Jet a shooting forth, and cf. Jutty.]
A jetty is any of a variety of structures used in river, dock, and maritime works that are generally carried out in pairs from river banks, or in continuation of river channels at their outlets into deep water; or out into docks, and outside their entrances; or for forming basins along the coast for ports in tideless seas. The forms and construction of these jetties are as varied as their uses, for they are formed sometimes of high open timber-work, sometimes of low solid projections, and occasionally only differ from breakwaters in their object. The term derived from the French word jetée, "thrown", and signifies something thrown out. Jetties at the coast that have been raised and extended help prevent long shore drift and therefore slow down beach erosion.
Chambers 20th Century Dictionary
jet′i, n. a projection: a kind of pier. [O. Fr. jettée, thrown out. See Jet (2).]
Dictionary of Nautical Terms
A name given in the royal dockyards to that part of a wharf which projects beyond the rest, but more particularly the front of a wharf, the side of which forms one of the cheeks of a dry or wet dock. Such a projection, whether of wood or stone, from the outer end of a wharf, is called a jetty-head.
