what are the terms if the bond under which the money is lent to antonio ?

The contract formed between Shylock and Antonio is the "Bond", wherein the conditions are in return for a loan of 3,000 ducats, Antonio shall repay Shylock in three months. Shylock doesn't charge any interest on his money. This is seen as a "generous" act given Shylock is a Jew. Under the unlikely event of "forfeiture", Antonio agrees to pledge one pound of his own Christian flesh to shylock.
