To anoint is to pour or smear with perfumed oil, milk, water, melted butter or other substances, a process employed ritually by many religions. People and things are anointed to symbolize the introduction of a sacramental or divine influence, a holy emanation, spirit, power or god. It can also be seen as a spiritual mode of ridding persons and things of dangerous influences, as of demons (Persian drug, Greek κηρες, Armenian dev) believed to be or to cause disease. Unction is another term for anointing. The oil may be called chrism.
