An unusual or abnormal sense of smell, often referring to a heightened ability to detect odors.
From exo- 'outside, external' + osme 'smell' (from Greek osphresis 'sense of smell'), possibly with -ia suffix for conditions. This is a rare medical or sensory term.
Though nearly forgotten, 'exosmia' captures something fascinating: some animals have smell receptors that detect chemicals from incredibly far away, giving them a kind of external sensory world beyond human imagination.
