Parvenu

A parvenu is a person who is a relative newcomer to a high-ranking socioeconomic class. The word is borrowed from the French language; it is the past participle of the verb parvenir (to reach, to arrive, to manage to do something). The Oxford English Dictionary defines a parvenu as: "A person from a humble background who has rapidly gained wealth or an influential social position; a nouveau riche; an upstart, a social climber. Also in extended use. Generally used with the implication that the person concerned is unsuited to the new social position, esp. through lacking the necessary manners or accomplishments." The term designates individuals not socially accepted by individuals already established in their new class. It expresses a form of classism. A social climber is a derogatory term that denotes someone who seeks social prominence through aggressive, fawning, or obsequious behavior. The term is sometimes used as synonymous with parvenu, and may be used as an insult, suggesting a poor work ethic or disloyalty to roots. Another synonym, with negative connotations, is arriviste.
