語源
英語の原文（Wiktionary）
From Middle English striven (“to strive”), from Old French estriver (“to compete, quarrel”), from Frankish *strīban (“to exert, make an effort”) from Proto-Germanic *strībaną, or from Frankish *stribēn (“to strive”) from Proto-Germanic *stribāną. As this verb is conjugated as if it were a strong verb (like drive, ride, and write), it is possible this word may instead be inherited from an unattested Old English *strīfan or *strifian, which would itself also be inherited from Proto-Germanic *strībaną.
