Water-girt land is a term used to describe an island, which is surrounded by WATER. It is derived from the combination of two words: 'WATER' and 'girt, ' which means 'ENCIRCLED.' This term is often used to describe islands that are completely surrounded by WATER, such as the Hawaiian Islands or the British Isles. The term can also be used to describe any landmass that is partially surrounded by WATER, such as the Florida Keys.
