From Middle English youren, from Old English eowerne. Displaced in standard speech by the -s form, yours. See also ourn, hern. Cognate with West Flemish joen (“yourn”).
- (obsolete outside Britain and US dialects, especially Appalachia) Yours.
1914, Edgar Rice Burroughs, The Mucker, All-Story Cavalier Weekly:
Your room's in there, back of the office, an' you'll find some clothes there that the last man forgot to take with him. You ken have 'em, an' from the looks o' yourn you need 'em.
