Apotrope (adj.: apotropaic) refers to objects such as amulets and talismans or other symbols intended to "ward off evil" or "avert or combat evil."

Usufruct from ancient Roman law (and now a part of many civil law systems), "usufruct" means the rights to the product of another's property. For example, a farmer may give a right of "usufruct" of his land to a neighbor, thus enabling that neighbor to sow and reap the harvest of that land.
-the right of using another’s property for profit, without spoiling its substance.
