English as a second or foreign language

English as a second or foreign language is the use of English by speakers with different native languages. Language education for people learning English may be known as English as a foreign language (EFL), English as a second language (ESL), English for speakers of other languages (ESOL), English as an additional language (EAL), or English as a New Language (ENL). The aspect in which EFL is taught is referred to as teaching English as a foreign language (TEFL), teaching English as a second language (TESL) or teaching English to speakers of other languages (TESOL). Technically, TEFL refers to English language teaching in a country where English is not the official language, TESL refers to teaching English to non-native English speakers in a native English-speaking country and TESOL covers both. In practice, however, each of these terms tends to be used more generically across the full field. TEFL is more widely used in the United Kingdom and TESL or TESOL in the United States. The term "ESL" has been seen by some to indicate that English would be of subordinate importance; for example, where English is used as a lingua franca in a multilingual country. The term can be a misnomer for some students who have learned several languages before learning English. The terms "English language learners" (ELL), and, more recently, "English learners" (EL), have been used instead, and the students' native languages and cultures are considered important. Methods of learning English are highly variable, depending on the student's level of English proficiency and the manner and setting in which they are taught, which can range from required classes in school to self-directed study at home, or a blended combination of both. In some programs, educational materials (including spoken lectures and written assignments) are provided in a mixture of English, and the student's native language. In other programs, educational materials are always in English, but the vocabulary, grammar, and context clues may be modified to be more easily understood by students with varying levels of comprehension.
