In the United States, a sophomore is a person in the second year at an educational institution, usually at a secondary school or at the college and university level, but also in other forms of post-secondary educational institutions. The term "sophomore" comes from the Greek words "sophos," meaning clever or wise, and "moros," which means foolish. In high school, a sophomore is equivalent to a tenth-grade or Class-10 student. In college, a sophomore is typically a student in their second year of college or university studies in the United States, typically 19 to 20 years old. College sophomores are advised to begin thinking of career options and to get involved in volunteering or social organizations on or near campus. In sports, sophomore may also refer to a professional athlete in their second season, while in entertainment, television series in their second season may be referred to as sophomore shows, while actors and musicians experiencing their second major success may be referred to as sophomore artists.
