Loughs, or lakes, are bodies of water that are surrounded by land. Synonyms for this word could include "ponds," which typically refer to smaller bodies of water, or "reservoirs," which are larger bodies of water that are typically created by damming a river. Other synonyms might include "basins," "coves," or "inlets," which all refer to bodies of water that are partially enclosed by land. Additionally, words like "fjord" or "estuary" might be used to describe bodies of water that are connected to the ocean and have unique characteristics, such as steep cliffs or saltwater mixtures. Ultimately, the specific term used to describe a body of water will depend on its size, shape, and location.
