Historically, common appendant means a tenant's right to graze animals on the landowner's land as a result of longstanding practice. The common appendant is founded on prescription. Common appendant is regularly annexed to arable land. The tenant was limited to such beasts, because such cattle were only wanted to plough and manure his land. Common appendant was deemed an incident to a grant of land, as of common right, and to enable the tenant to use his plough land.
