In 1916, the German psychologist Hans Hanning wrote in the monograph "The smell": "The abstraction of the smell is impossible." Indeed, we easily call white and the flowers of the valley, and snow, and paper. We can describe the sweet taste of sugar, honey or chocolate adjectives. But for smells, there are no adjectives abstracted from the name of the source of the smell. We are talking about a lemon, mint, flower, almond smell, each time mentioning a “reference” source of such a smell.
