Mooth
- often used to describe the outfall or lower end of a stream, river, estuary or inland sea, Scots mooth occurs in early place-names that pre-date the oldest Scots literature. The mouth of the Tweed is recorded as Twedemud around the year 1220, and as Twedemouth in 1337. Old documents can also show how place-names have evolved. In 1702, the Records of the Convention of the Royal Burghs of Scotland noted the Building of ane harbour in the moueth of Lossie, giving an insight into the history of the name of the Moray Firth harbour town now called Lossiemouth.
