والروائح وأنواعها كثيرة، وليست لها أسماء مخصوصة
Odors are numerous in kind, without separate established names for all of them.
Odor illustrates that a sensible quality may be distinguishable even when language lacks a unique name for every nuance. Some smells are pleasant, others unpleasant, and others are perceived as mixtures.
Having a conventional word for a quality and perceiving that quality are different matters. The limits of vocabulary do not by themselves set the limits of possible sensible distinctions.
