An amulet, also known as a "good luck charm", 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 gems, statues, coins, drawings, plant parts, animal parts, and written words. Amulets which are said to derive their extraordinary properties and powers from magic or those which impart luck are typically part of folk religion or paganism, whereas amulets or sacred objects of formalised mainstream religion as in Christianity are believed to have no power of their own without being blessed by a clergyman, and they supposedly will also not provide any preternatural benefit to the bearer who does not have an appropriate disposition. Amulets are different from talismans and charms because they may have alleged magical powers other than protection. Amulets are sometimes confused with pendants, small aesthetic objects that hang from necklaces. Any given pendant may indeed be an amulet but so may any other object that purportedly protects its holder from danger.
