Word Origin & Etymology

From Old English 'underwritan', a loan-translation of Latin 'subscribere' ('to write below'). Its modern financial sense arose in the 17th century at London coffeehouses, where marine insurers literally wrote their names and the amount of risk they would cover at the bottom of a shipping policy.
