I apologize in advance that the esoteric nature of my daily life leads me to think that posting a glossary might be useful.
These definitions are borrowed, edited, and augmented for my own purposes mostly from the SFZC City Center Residents’ Handbook; and from the Ino’s blog (which you are encouraged to visit, often), here:
