English as Second Language (ESL)

English as a Second Language (ESL) refers to the study or instruction of English for speakers of other languages, typically occurring in a region where English is the dominant or official language. Gaining prominence in the mid-20th century alongside the rise of English as a global lingua franca, the term is used to describe both the learners and the specific educational programs designed to facilitate their linguistic acquisition for academic, professional, or social integration.

Usage of the term has become a subject of debate within linguistics and pedagogy. Proponents and administrators often retain the label for its historical clarity, widespread public recognition, and established legal definitions in funding structures. However, critics argue that the specific phrasing is often factually inaccurate, as English may be a student's third or fourth language rather than their second. Furthermore, some advocates prefer asset-based terminology, arguing that ESL focuses on a deficit (the lack of English) and implies a hierarchy, whereas newer terms emphasize the student's existing multilingual capabilities.

Example:
"The district is hiring three new instructors for the ESL department to support the influx of international students."

Example:
"While she speaks French and Arabic fluently, she is currently enrolled in ESL night classes to improve her professional writing."
