Usage: Contention, Strife. A struggle between two parties is the idea common to these two words. Strife is a struggle for mastery; contention is a struggle for the possession of some desired object, or the accomplishment of some favorite end. Neither of the words is necessarily used in a bad sense, since there may be a generous strife or contention between two friends as to which shall incur danger or submit to sacrifices. Ordinarily, however, these words denote a struggle arising from bad passions. In that case, strife usually springs from a quarrelsome temper, and contention from, a selfish spirit which seeks its own aggrandizement, or is fearful lest others should obtain too much. Strife has more reference to the manner than to the object of a struggle, while contention takes more account of the end to be gained.
