A more thorough explanation:

Definition: A traitor is a person who commits treason against their country or betrays a person, cause, or obligation.

Examples:

• Julius and Ethel Rosenberg were convicted of being traitors to the United States for passing atomic secrets to the Soviet Union during the Cold War.
• Benedict Arnold is known as a traitor in American history for betraying the Continental Army during the Revolutionary War.

The examples illustrate how a traitor is someone who goes against their country or a cause they are supposed to support. In the case of the Rosenbergs, they betrayed their country by giving away important information to another nation. Benedict Arnold betrayed the Continental Army by trying to help the British during the Revolutionary War.

Definition: A tramp is a person who roams from place to place without a job or visible means of support.

Example: The man walking along the highway with a backpack and no destination in mind is a tramp.

This example shows how a tramp is someone who wanders around without a clear purpose or job. They may beg for money or food to survive, but they do not have a stable source of income or a permanent home.

Definition: A tramp steamer is a cargo ship that does not have a fixed schedule or route and travels wherever there is cargo to be transported.

Example: The tramp steamer picked up a load of bananas in South America and then sailed to Europe to deliver them.

This example illustrates how a tramp steamer is a ship that does not follow a set schedule or route. Instead, it travels wherever there is cargo to be transported. This type of ship is often used for transporting goods that do not require a specific delivery date or time.
