UNFRIENDLY°

noun (Politics) A hostile person or thing; in military jargon, an enemy. Etymology: Formed by treating the adjective unfriendly as a noun; in the military usage there could be some influence from the adjective friendly meaning 'fighting on one's own side'. History and Usage: Unfriendly was first used as a noun in the seventies. Apart from the military usage recorded here, it has been used to refer to any hostile person or thing (for example, a hostile take-over bid or an attacking rogue program such as a virus). The old model [missiles] you can buy...Makes a big difference if the friendlies or the unfriendlies get 'em, and what kind of encoding hardware, computer directors, and so on go with 'em. S. F. X.
