1) A word of French origin which had several related shades of meaning. It could refer to swine fodder such as acorns or beech mast, in which sense Chaucer used it in <i>c</i>.1374 (OED) or it could be the right to pasture swine in the forest. Finally it was often the payment made for that privilege.
In 1245-6, for example, Thomas de Auno had pannage in his woods at Burneston valued at 6d. In Pickering, in 1250-1, the tenants had mast for their swine without paying ‘pannage’: et pessonem ad porcos suos sine pannagio reddendo.
