FWIW, when teaching Git I have found that users immediately understand
"staging area", while "index" and "cache" confuse them.
"Index" means to them a numerical index into a data structure.
"Cache" is a local copy of something that exists remotely. Neither
word describes the concept correctly from a user's perspective.
I learned long ago to type "index" and "cached", but when talking (and
thinking) about Git I find "the staging area" gets the point across
very clearly and moves Git from interesting techie-tool to
world-dominating SCM territory. I'm surprised that that experience
isn't universal.
