1911 Encyclopædia Britannica/Urdū

URDŪ, the name of that variety of Hindostani which borrows a great part of its vocabulary from Persia and Arabic, as contrasted with “Hindi,” the variety which eschews such words, but borrows from Sanskrit instead. It is spoken by Mussulmans and those Hindus who have come under Mussulman influences, and has a considerable literature. See Hindostani and Hindostani Literature.
