Jamieson's major work, the
Etymological Dictionary of the Scottish Language appeared in 2 vols. in 1808. A meeting the Danish scholar
Grim Thorkelin had suggested this work, and, working with
Thomas Ruddiman's glossary to
Gavin Douglas's version of the
Aeneid, Jamieson completed the work almost alone. He prepared an abridgment in 1818 (reissued in 1846 with a memoir by John Johnstone), and aided by numerous others, he added two supplementary volumes in 1825. The work drew on folklore and provincialisms. The introductory antiquarian dissertation supported a theory on the
Pictish influence on the
Scots language. A revised edition by
John Longmuir and David Donaldson was issued in 1879–87. These volumes remained the standard reference work for the Scots language until the publication of the
Scottish National Dictionary in 1931. Jamieson's other works included: •
Socinianism Unmasked, 1786. •
The Sorrows of Slavery, 1789, a pamphlet on the
African slave trade •
Sermons on the Heart, 2 vols., 1791. Around the same time as
The Sorrows of Slavery. •
Congal and Fenella, a Metrical Tale, 1791. •
Vindication of the Doctrine of Scripture, in reply to
Joseph Priestley's
