yield: [OE] Yield is descended from prehistoric Germanic *gelthan ‘pay’, which also produced German gelten ‘pay’ (German geld ‘money’ comes from the same base). It originally meant ‘pay’ in English too, and it seems the sense ‘surrender’, which emerged in the 13th century, may be due to the influence of French rendre ‘give’, which is used reflexively for ‘surrender’.
