An adult is a person who has attained the age of majority, legally recognized as being responsible for their actions and capable of engaging in contracts and other legal responsibilities.
The age at which a person can enter into binding contracts or agree to other legal acts without the consent of another adult. In most states, the legal age, also called the age of majority, is 18 years.
The term 'majority' can refer to more than half of a group, especially in voting contexts, or the age at which a person is considered legally independent and responsible for their actions.
