Fastai code abbreviation glossary

Jeremy mentioned in one of the lectures it’s good to learn Greek letter names, because it helps reading the math equations if we can verbalize them in our head. I think the same applies to reading fastai code. If I can deduce the variable/attribute/class name etc., it’s much easier to follow along. E.g. ftrs = features. I have a problem with many abbreviations though - I can’t make them into an English word. Could we do a Wiki post and crowdsource fastai code glossary?

We actually already have an abbreviation guide:

lf - loss function?
lam - lambda?

I believe just a PR to this markdown file should be sufficient:
