The Scottish National Dictionary Association (SNDA) was founded in 1929 to foster and encourage the use of the Scots language, in particular by producing a scholarly dictionary of modern Scots. This primary aim was fulfilled in 1976 with the completion of the 10-volume Scottish National Dictionary (SND), covering the language from 1700 to 1976. Material for SND is drawn from a wide variety of written and oral sources of Lowland Scots from Shetland to Ulster. SND was produced under the editorial direction of William Grant, and of David Murison.
