(The Old Celtic name, possibly meaning “cleanse”, may have derived from the [[Indo-European]] ''clou'', and was also possibly the name of a river goddess. The [[Roman]] historian [[Tacitus]] refers to it as the ''Clota''. It became the Gaelic ''Clutha''. Today it is the ''Cluaidh''. The word “Firth” used by the Scots to describe an estuary or arm of the sea derives from the Old Norse. It has the same root as “fiord”.} | (The Old Celtic name, possibly meaning “cleanse”, may have derived from the [[Indo-European]] ''clou'', and was also possibly the name of a river goddess.
