When people—English speaking people, anyway—describe odors, what they are actually doing much of the time is describing the source of the odor. Orange-y. Smokey-. Skunk-y. This seems natural enough, but it’s fundamentally different from how we describe other sensory experiences. Words like “white” and “round” describe visual features of an object, not the object itself. It could be a baseball, or it could be the Moon. In the same way, a tone can be “high-pitched” whether it comes from a bird or a teakettle.
