Latino is often the preferred noun or adjective for a person from, or whose ancestors were from, a Spanish-speaking land or culture or from Latin America. Latina is the feminine form. Some prefer the recently coined gender-neutral term Latinx, which should be confined to quotations, names of organizations, or descriptions of individuals who request it and should be accompanied by a short explanation. For groups of women, use the plural Latinas; for groups of men or of mixed gender, use the plural Latinos.
Hispanic refers to a person from — or whose ancestors were from — a Spanish-speaking land or culture. Latino, Latina, or Latinx are sometimes preferred. Follow the person’s preference. Use a more specific identification when possible, such as Cuban, Puerto Rican, or Mexican American.
Chicano is a term that Mexican Americans in the U.S. Southwest sometimes use to describe their heritage. Use only if it is a person’s preference.
