The property or quality of a thing that affects, stimulates, or is perceived by the sense of smell.
A sensation, stimulation, or perception of the sense of smell.
odour
the property of certain substances, in very small concentrations, to stimulate chemical sense receptors that sample the air or water surrounding an animal. In insects and other invertebrates and in aquatic animals, the perception of small chemical concentrations often merges with perception via contact of heavy concentrations (taste), and with other chemoreceptive specializations. See also smell.
