File tracking states

A specified file can be in one of four states

State	Explanation
Untracked	The file is not tracked by git and changes are not recorded
Unmodified	The file is tracked by git and has not changed since it's last commit
Modified	The file is tracked by git and has changed since it's last commit
Staged	means that you have marked a modified file in its current version to go into your next commit snapshot.

File tracking lifecycle

Why is it called Git?

Linus Torvalds has quipped about the name "git", which is British English slang for a stupid or unpleasant person. Torvalds said: "I'm an egotistical bastard, and I name all my projects after myself. First 'Linux', now 'git'."
