A more thorough explanation:

Definition: Full age refers to the age at which a person attains full legal rights, especially civil and political rights such as the right to vote. It is usually defined by statute as 18 years old, which is also known as the age of majority.

Examples:

• A person who is 18 years old is considered to be of full age and has the legal right to vote, sign contracts, and make other important decisions.
• Some states allow a person to make certain personal decisions at an earlier age than the general age of capacity, such as the decision to marry or write a will. For example, the age of capacity to write a will is typically 14 years old.
• If a person over the age of consent (usually 16 years old) has sexual intercourse with a person under the age of consent, the older person may be prosecuted for statutory rape regardless of whether the younger person consented to the act.

The examples illustrate that full age is an important legal concept that determines a person's ability to make decisions and exercise their rights. It is usually defined by statute and varies depending on the specific context, such as the age of consent or the age of criminal responsibility.
