As in any specialized profession, the world of ESL/EFL/ELL has its own unique terminology. I quite regularly come upon words that I’m not familiar with.
I thought a short “The Best…” list might be useful for readers.
I haven’t found one glossary of these kinds of terms that I would consider “complete” and accessible, so I’m listing a few of them.
Here are my picks for The Best Guides To ESL/EFL/ELL Terminology:
The American Institutes For Research has a good document titled Common ELL Terms and Definitions.
Colorin Colorado has a good glossary.

An ELT Glossary comes from An ELT Notebook.
The NILE ELT Glossary is also good, though you have to register (for free) to access it.
A SHORT GUIDE TO ACRONYMS IN ELT is from EFL Magazine.
Here’s a glossary of terms related to immigration and education.
Clarifying Multilingual Terminology is by Jana Echevarria.
Other suggestions are, as always, welcome.
