JETTY

n. wall built out into the water to protect a harbor; landing pier

adj. made of jet; that looks like a deep black color

The term jetty, derived from the French jetée, and therefore signifying something thrown out, is applied to a variety of structures employed in river, dock, and maritime works which 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 sea-coast for ports in tideless seas. The forms and construction of these jetties are as varied as their uses; for though they invariably extend out into water, and serve either for directing a current or for accommodating vessels, they are sometimes formed of high open timber-work, sometimes of low solid projections, and occasionally only differ from breakwaters in their object .
