"어른" is the Korean word for "adult." It refers to individuals who have reached maturity, typically recognized as being over the age of 18. In many cultures, including Korean society, adults are expected to take on responsibilities such as work, family care, and community involvement. In South Korea, the transition from childhood to adulthood is marked by various ceremonies, such as the 성년식 (coming-of-age ceremony). This event celebrates the individual's new status and responsibilities. Adults play a crucial role in shaping society, guiding younger generations, and contributing to the economy and culture.
