The English meaning of feculent came as a shock. I am used to the French equivalent, differing only by an accent, which means simply 'starchy' and is applied to things like potatoes, pasta and beans. The Latin origin is the same; strange that dregs came to mean starch! When I logged in to comment I was amused, given the context, to find that an advert popped up "Stools - 24Hr delivery" - but not the feculent kind of stools!
