The Scots word derives directly from the Gaelic "Clarsach" which means "A harp" of any type; in English usage, it refers exclusively to the traditional small harp. "Clarsach" should be pronounced as "Klahrssahch" in English, with almost even stress on the two syllables and where:
"ah" is pronounced as in "shah";
"ss" is as in "less"; and
"ch" is as in "loch".
