Community team and network team are constructing glossaries in parallel
https://trac.torproject.org/projects/tor/wiki/doc/community/glossary
https://gitweb.torproject.org/torspec.git/tree/glossary.txt
I wonder if there's some way to team up!
(For bonus points, there is a thing on gitweb called a glossary: https://gitweb.torproject.org/tor-glossary.git/tree/ but it looks less advanced than either of the above two.)
