Synonym Usage
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.

Explanation
An odor is anything you can smell — like a scent or an aroma. If you sniff a sour odor in your gallon of milk, you should probably pour it down the sink instead of drinking it. Most people are more likely to use the word odor for unpleasant smells, like the odor of your uncle's stinky cigars or the musty odor in your grandmother's attic. You can also use the word odor in a figurative way, to mean a feeling or impression given by something: "The whole bank seemed full of the odor of money and greed." Odor is Latin, meaning "a smell or a scent."
