Sir John Morris-Jones (born Oct. 17, 1864, Llandrygarn, Anglesey, Wales—died April 16, 1929, Bangor, Caernarvonshire) was a teacher, scholar, and poet who revolutionized Welsh literature. By insisting—through his teaching and his writings and his annual adjudication at national eisteddfodau (poetic competitions)—that correctness was the first essential of style and sincerity the first essential of the literary art, he helped restore to Welsh poetry its classical standards.
The eldest son of Morris Jones, a shopkeeper, he gave up the study of mathematics in order to devote his entire time to Welsh language and literature. After graduation from the University of Oxford, Jones became the first professor of Welsh at the University College of North Wales, Bangor. When he was knighted in 1918, he began styling himself Morris-Jones.
His works include A Welsh Grammar, Historical and Comparative (1913), Cerdd Dafod (1925; “The Art of Poetry”), Orgraff yr Iaith Gymraeg (1928; “The Orthography of the Welsh Language”), and an unfinished study of syntax (1931), published posthumously under the title Welsh Syntax. Caniadau (1907; “Poems”), his collected poems, contains a number of fine translations into Welsh, most notably the robāʿīyāt of Omar Khayyam, a translation directly from the Persian.
