the.com/tray
a humble flat plane that quietly prevents a thousand spilled disasters per shift.
means a flat, shallow receptacle with a raised rim, used for carrying, holding, or serving items.
from From Old English "trīg" or "trēg," meaning a wooden board or flat container, likely related to "trēow" — the word for "tree" — since the earliest trays were simply boards hewn from wood. So the humble cafeteria tray carries, in its name, the memory of the forest it once was.
