Lochs, a Scottish word for lakes, can be referred to using several other words, including waters, meres, tarns, or loughs. In Ireland, lough is the term used for lakes, and in Wales, they are referred to as llyn. Other synonyms for lochs include reservoirs, ponds, or basins. Depending on the size of the body of water, it may be referred to as a pond, the smallest of all, or a sea loch, which is a body of saltwater inlet connected to the sea. Whatever their name, these natural features are a significant part of Scotland's landscapes and a popular tourist attraction because of their beauty and historic significance.
