Odor
An odor or odour or fragrance is caused by one or more volatilized chemical compounds, generally at a very low concentration, that humans or other animals perceive by the sense of olfaction. Odors are also commonly called scents, which can refer to both pleasant and unpleasant odors. The terms fragrance and aroma are used primarily by the food and cosmetic industry to describe a pleasant odor, and are sometimes used to refer to perfumes. In contrast, malodor, stench, reek, and stink are used specifically to describe unpleasant odor. The term smell (in its noun form) is used for both pleasant and unpleasant odors.In the United Kingdom, odour refers to scents in general. In the United States and for many non-native English speakers around the world, odor generally has a negative connotation, as a synonym for stink; on the other hand, scent or aroma are used by those people to indicate ""pleasant smells"".
