An adult is an individual who has reached the age of legal majority, which varies by country but generally refers to someone who is considered mature and responsible enough to manage their own affairs, such as voting, entering into contracts, and being held accountable for their actions. This age can range from 18 to 21 years old, depending on the legal system and the specific rights and responsibilities associated with adulthood. In addition to legal definitions, adulthood also encompasses emotional, psychological, and social maturity.
