A more thorough explanation:

Definition: To carry out, perform, or complete as required, usually to fulfill an obligation. This can include:

1. Executing a contract or order
2. Signing or completing all formalities necessary to make a contract or document effective
3. Putting to death according to a court-rendered sentence
4. Enforcing a monetary judgment

Examples:

• John was hired to execute the company's marketing plan.
• The lawyer executed the contract by signing and delivering it to the client.
• The state executed the convicted murderer by lethal injection.
• The court ordered the defendant to execute the payment of the monetary judgment.

These examples illustrate how execute can be used in different contexts, such as business, law, and criminal justice. In each case, execute means to carry out or fulfill an obligation, whether it's a marketing plan, a contract, a court sentence, or a monetary judgment.
