Malodorous
adjective /mælˈəʊdərəs/ — Smelling very unpleasant — and by extension, morally suspect.
Definition
Smelling very unpleasant; having an offensive odor; (informal) morally offensive or corrupt.
Beyond the definition
Malodorous does double work — the literal unpleasant smell and the moral application (a malodorous deal, a malodorous arrangement). The metaphor is very old: corruption and bad smell have always been associated. The moral sense came free with the olfactory one.
Origin & history
From Latin malus (bad) + odor (smell). The bad smell — named simply and directly. Bad + smell = the word.

Dignified Deteriorating Chair

A wooden chair on the forest floor is covered in moss and mushrooms, slowly breaking down into the damp earth.
