The word that’s been stuck in my head, and an epic way to say ‘rubble’? Read this week in The Children of Men by P. D. James.
detritus |diˈtrītəs| (noun)
waste or debris of any kind: streets filled with rubble and detritus.
• gravel, sand, silt, or other material produced by erosion.
• organic matter produced by the decomposition of organisms.
ORIGIN late 18th cent. (in the sense ‘detrition’): from French détritus, from Latin detritus, from deterere ‘wear away.’
