Teaching English as a Second Language

let's define it in different ways

Teaching English as a second language (TESL) refers to teaching English to students whose first language is not English. The teaching profession has historically used different names for TEFL and TESL; however, the more generic term teaching English to speakers of other languages (TESOL) is increasingly used to describe the profession. It covers both TESL and TEFL as umbrella terms.[4] Both native speakers and non-native speakers successfully train to be English language teachers. To teach English as a Second Language to English Language Learners, or ELLs, passing a written and oral test in English to demonstrate proficiency is often recommended, but not always required.[6]
