I would describe a faint sound as being quiet, and recently I wished to express the idea of quietness for smells. I wanted a word like faint but specific to smells (or smells and tastes if such does exist). An example sentence might be
This tarmac is _____ after the rain
Does such a word exist?
This similar question asks about things that have no smell at all. While similar I am seeking to describe something that does have a smell albiet a faint one.
