polymath

n. one who is learned; highly-educated person

A polymath (Greek polymathēs, πολυμαθής, "having learned much") is a person with encyclopedic, broad, or varied knowledge or learning. The dictionary definition is consistent with informal use, whereby someone very knowledgeable is described as a polymath when the term is used as a noun, or polymath or polymathic when used as adjectives. It especially means that the person's knowledge is not restricted to one subject area. The term is used rarely enough to be included in dictionaries of obscure words.
