Barbarian is a term for an uncivilized person, often used pejoratively, either in a general reference to a member of a nation or ethnos, typically a tribal society as seen by an urban civilization either viewed as inferior, or admired as a noble savage. In idiomatic or figurative usage, a "barbarian" may also be an individual reference to a brutal, cruel, warlike, insensitive person. The term originates in the ancient Greek civilization, meaning "anyone who is not Greek". Comparable notions are found in non-European civilizations. Barbarism refers to a non-standard word, expression or pronunciation in a language, particularly an error of morphology, while a solecism is an error of syntax. The term is used prescriptively in writing. With no accepted technical meaning in formal linguistics the term is little used by descriptive scientists.
