Look that up in your Funken Wagnalls: Coffers
Reading an article about business plans, came across the word “coffers” as in “Black Friday Blowouts help divert money from your competitors to your own coffers” – or something to that effect.
I understand that in this context it normally means “strongbox” or more accurately “Financial resources”;
However, look at what it means in architecture; “A decorative sunken panel in a ceiling, dome, soffit, or vault.”
Hmmm, sounds like a good place to hide your coffers!
