ENL: English as a Native language, people who were born with English as their first/only language and have no other need for other languages in principle.
ESL: English as a second language, people who have learned English as an addition to their first language and need English for any reason in their daily life.
EFL: English as a foreign language, people who are learning English, but have no need for it in their daily life, they may need for business or when traveling to other countries.
