Leave it to the English to try to rescue fine old words that have fallen on hard times.
My favorite in this collection is "skirr", the whirring sound of birds' beating wings. Give that to a poet as a present. He'll thank you.
"Recrement" also seems serviceable. After all, "waste matter" is not always sufficiently, shall we say, redolent of the reality. "Griseous" is a happy discovery worthy of revivification, don't you think? "Streaked with grey" is just too cumbrous a synonym.
For my own part, I would like to propose a few dear old words that reside in the Chapman Home for Semi-Retired Words. With a little exercise and refurbishment they could be put back on the road. There is, for example, "pullulation", the busy action of many participants; as, for example, what an ant hill does. (E.g., "The campaign office pullulates with volunteers.")
Another underappreciated latinate word is "scrofulous", an appearance of disease or contamination. It is the sort of thing that eventually might characterize the uncleared "recrement" in your kitchen sink.
