ELT – English Language Teaching
ESL – English as a Second Language
EFL – English as a Foreign Language
The main difference between these are that ESL is English taught to foreign language speakers living in an English speaking country like The United States, Canada, England, Australia, etc. English as a foreign language, on the other hand, is taught to those wishing to learn English for their study/work/hobby needs but who live in countries where English is not the first language.
