EFL or English as a Foreign Language is a term commonly used to describe the learning or teaching of English by non-native speakers in countries where English is not the native language. There are several synonyms for EFL, including ESL (English as a Second Language), ESOL (English for Speakers of Other Languages), and TEFL (Teaching English as a Foreign Language). Each of these terms refers to the same concept of learning and teaching English as a non-native language. While they have slightly different nuances, they are often used interchangeably in academic and educational circles. Whatever term is used, the goal remains the same - to provide a pathway for non-native speakers to achieve fluency in English.
