saddlebag, knapsack; pannier (basket or bag fastened to the back of a bicycle or pack animal)
“Acudió Sancho a su asno para sacar de las alforjas con qué limpiarse y con qué curar a su amo, y como no las halló estuvo a punto de perder el juicio: maldíjose de nuevo y propuso en su corazón de dejar a su amo y volverse a su tierra, aunque perdiese el salario de lo servido y las esperanzas del gobierno de la prometida ínsula.” — Sancho ran to his ass to get something wherewith to clean himself out of his saddlebags, and relieve his master; but not finding them, he well-nigh took leave of his senses, and cursed himself anew, and in his heart resolved to quit his master and return home, even though he forfeited the wages of his service and all hopes of the promised island.
From Andalusian Arabic الخُرْج (al-ḵurj), from Arabic خُرْج (ḵurj, “saddlebag”).
