amulet

An amulet, also known as a good luck charm or phylactery, is an object believed to confer protection upon its possessor. The word "amulet" comes from the Latin word amuletum, which Pliny's Natural History describes as "an object that protects a person from trouble". Anything can function as an amulet; items commonly so used include statues, coins, drawings, plant parts, animal parts, and written words.
