Synonym Study

Odor, smell, scent, stench all refer to sensations perceived through the nose by the olfactory nerves. Odor and smell in literal contexts are often interchangeable. Figuratively, odor also usually occurs in positive contexts: the odor of sanctity. Smell is the most general and neutral of these two terms, deriving connotation generally from the context in which it is used: the tempting smell of fresh-baked bread; the rank smell of rotting vegetation. In figurative contexts smell may be either positive or negative: the sweet smell of success; a strong smell of duplicity pervading the affair. Scent refers either to delicate and pleasing aromas or to faint, barely perceptible smells: the scent of lilacs on the soft spring breeze; deer alarmed by the scent of man. Stench is strongly negative, referring both literally and figuratively to what is foul, sickening, or repulsive: the stench of rotting flesh; steeped in the stench of iniquity and treason.
