The term 'HARBOR WALL' can be broken down into two words, 'HARBOR' and 'WALL'. The first word, 'HARBOR', is defined as a sheltered area of water where ships can dock and unload cargo. The second word, 'WALL', is defined as a structure built to provide protection or support. When combined, the term 'HARBOR WALL' refers to a WALL built around a HARBOR to protect it from the elements and provide support for ships docking in the HARBOR. One example of a HARBOR WALL is a JETTY, which is a structure built out into the water to protect a HARBOR from the waves and currents of the sea.
