To search this glossary for (e.g.)

If you want the definition of a term you came across on the site, please add it to the list of proposed glossary entries, and (hopefully) someone will define it.
To those who follow a link here: If you see an answer that's inaccurate or misleading, or could be better, please go ahead and modify it if you have the knowledge.
