persons, contracts. This word has several significations. 1. A person born out of the United States; but in this sense the term alien is more properly applied, until he becomes naturalized. 2. A person who is not privy to an act or contract; example, he who is a stranger to the issue, shall not take advantage of the verdict. 2. When a man undertakes to do a thing, and a stranger interrupts him, this is no excuse. Com. Dig. Condition, L 14. When a party undertakes that a stranger shall do a certain thing, he becomes liable as soon as the stranger refuses to perform it.
