ESOL (English for Speakers of Other Languages) is a term that refers to teaching and learning English as a second language. In some regions, ESOL is known as English as a Foreign Language (EFL) or English as a Second Language (ESL). Other synonyms for ESOL include English Language Learners (ELL), Limited English Proficient (LEP), and Non-native English Speakers (NNES). The term ESOL is commonly used in the United Kingdom and Australia, while EFL is widely used in Asia and Europe. Additionally, ESL is often used in North America, where the majority of immigrants originate from Spanish-speaking countries. Despite their different names, these synonyms all refer to the same aim - providing language instruction to individuals who are not native English speakers.
