A: ESL stands for "English as a Second Language." It refers to the teaching and learning of English by non-native speakers who reside in English-speaking countries or plan to travel to English-speaking countries. ESL programs are designed to help non-native speakers improve their reading, writing, speaking, and listening skills in English. ESL courses may cover a range of topics, from basic grammar and vocabulary to advanced academic writing and professional communication. ESL programs may be offered by schools, universities, language institutes, or online platforms. The goal of ESL instruction is to help non-native speakers achieve proficiency in English so that they can communicate effectively and achieve their personal, academic, and professional goals.
