Does git “dirty” mean files not staged, or not committed? (glossary conflict)

Question

https://www.kernel.org/pub/software/scm/git/docs/gitglossary.html#def_dirty A working tree is said to be \"dirty\" if it contains modifications which have not been committed

Answer 1

From torek's answer:

What git status tells you is both the answer to:

• "what, if anything, is staged for commit" and
• "what, if anything, is different between the work-tree and the index".

Note that only the working tree is involved with git status, not the "working directory".

Git 2.9.1+ (Q3 2016) will make that clearer.
See commit 2a0e6cd (09 Jun 2016) by Lars Vogel (vogella).

Use "working tree" instead of "working directory" for git status

Working directory can be easily confused with the current directory.
In one of my patches I already updated the usage of working directory with working tree for the man page but I noticed that git status also uses this incorrect term.
