Loch

Loch (/ˈlɒx/) is the Irish and Scottish Gaelic word for a lake and a sea inlet. It is cognate with the Manx lough, Cornish logh, and the Welsh word for lake, llwch.

In English and Hiberno-English, the anglicised spelling lough is commonly found in place names, pronounced the same way as loch. In Scottish English, 'loch' is always used.
