An "alcoholic" is a person who has a strong dependence on alcohol, which can lead to significant physical and psychological issues. This condition is often characterized by an inability to control drinking, cravings for alcohol, and withdrawal symptoms when not consuming it. Alcoholism can affect various aspects of life, including relationships, work, and health. It is considered a chronic disease that may require treatment, such as counseling or support groups like Alcoholics Anonymous, to help individuals manage their addiction and work towards recovery.
