ELL: English Language Learning

ESL: English as a Second Language

ESOL: English for Speakers of Other Languages

EFL: English as a Foreign Language 

MIT strives...

to be inclusive of all English language speakers, regardless of fluency and level of the learner. Thus, we have chosen to entitle this guide English Language Resources, to serve anyone who desires to improve their English skills. The term ESL can be exclusive to those learners of English who may know more than one other language, and isn't the best fit for everyone. However, many of the organizations/sites on this guide still use the term ESL to refer to those learning English. In order to remain consistent with the external sites use of the different acronyms listed above, this guide reflects whichever term is used by the organization/site.
