"But haeretidtamentum, hereditament, is the largest word of all in that kind; for whatsoever may be inherited is an hereditament, be it corporeal or incorporeal, real or personal or mixt." 12

"An heirloom, though neither land nor tenement, but a mere moveable, yet being inheritable, is comprised under the general word, 'hereditament' and a condition, the benefit of which may descend to a man from his ancestor, is also an hereditament." 13

Hereditaments are divided into corporeal and incorporeal hereditaments. Most authors on real property state the distinction between corporeal and incorporeal hereditaments to be that the former is the thing itself and the latter only some interest in it. This view is however, entirely erroneous, as hereditaments of either class, are merely interests in the land.
