What does pallium mean?
A pallium most commonly refers to the narrow white woolen band worn by the pope and metropolitan archbishops, signifying ecclesiastical authority. The word also has older and specialized meanings. Historically, it meant a cloak or mantle, especially the garment associated with Roman officials. In zoology, a pallium is the mantle-like covering of a mollusc, while in anatomy the term can denote the cerebral cortex, the brain’s outer layer. The ecclesiastical and historical senses are the most readily recognized, whereas the zoological and neurological uses are technical. Because “pallium” links a formal vestment with an ancient Roman garment and with scientific terminology for coverings, it is a useful example of how a single word can preserve several distinct areas of meaning.

Where does pallium come from?
English borrowed the word from Latin pallium, meaning “cloak” or “covering,” a term associated with a garment worn by Roman officials. Its ecclesiastical use developed from the pallium as a sign of authority, eventually becoming a distinctive band worn by the pope and metropolitan archbishops. Related English forms include pall and palliate, while pallial is used in zoological terminology.
