1) In Yorkshire, this was formerly the usual word for market-place.
In 1324, William de la Lee sued Thomas de Totehill ‘for assaulting him in the town of Wakefield, in a certain place called le Markethstede’ and references in other towns include: 1386 un burgagio in Ripon in le Marketstede
1421-2 the Marketstyde, Knaresborough and 1507 my howse in the Markett stede, Pickering. From the early 1500s it overlapped with ‘market-place’: property in Knaresborough that was held by the Henlake family was described in 1611 as lying in the market stede, whereas in 1637 it was in the market place. When Huddersfield was granted market rights in 1671 it had a market-place not a marketstead. However, the word survived in the vernacular into the eighteenth century at least: 1724 a house … in the markett stead, Skipton.
