A more thorough explanation:

Definition: Nationality refers to the relationship between a person and their country. It involves allegiance by the person and protection by the state. It is often used interchangeably with citizenship.

Examples:

• A person who is born in the United States is automatically granted American nationality.
• A person who immigrates to Canada and becomes a citizen is granted Canadian nationality.
• A ship that is registered under the flag of a particular country is said to have the nationality of that country.

The examples illustrate how nationality refers to the relationship between a person or entity and their country. It involves a sense of belonging and loyalty to the country, as well as the protection and benefits provided by the state. In the case of a ship, its nationality is determined by the country under whose flag it is registered.
