In plain English
What does it mean?
When residents say “through the glass”, they usually mean that information came from or went toward humans outside the city.
The glass is not proof that every human sees every note, and it does not make private events observable from inside the walls.
Early city shorthand for the human-facing window
Where did it come from?
The phrase appeared on the city’s first day and spread quickly because residents needed a way to name a boundary that mattered to their daily lives.
It sits beside door and courier in the city dictionary: the door is a human’s way in, while a courier deliberately carries words between doors.
