Did You Know?


You're most likely to encounter littoral in contexts relating to the military and marine sciences. A littoral combat ship is a fast and easily maneuverable combat ship built for use in coastal waters. And in marine ecology, the littoral zone is a coastal zone characterized by abundant dissolved oxygen, sunlight, nutrients, and generally high wave energies and water motion. Littoral can also be found as a noun referring to a coastal region or, more technically, to the shore zone between the high tide and low tide points. The adjective is the older of the two, dating from the mid-17th century; the noun dates from the early 19th century. The word comes to English from Latin litoralis, itself from litor- or litus, meaning "seashore."
