Does anyone have the definitive reason for the calling of a poop a stool?
I have sat and pondered this for many years...
:-)
From the dictionary:
Originally used of thrones (cf. cynestol "royal seat, throne"); change of meaning began with adoption of chair from French, which relegated stool to small seats without arms or backs, then "privy" (early 15c.) and thence to "bowel movement" (1530s).
or possibly from here:
Long wisps fall across her forehead as she sits very straight on her stool, her narrow shoulder blades drawnback elegantly.
