olfactory
ohl-FAK-tuh-ree
/ɒlˈfæktəri/
Relating to the sense of smell.
This anatomical term refers to the entire biological system responsible for detecting odors, which plays a massive role in how we perceive food flavors.
The story behind the word. The word 'olfactory' comes from the Latin 'olfacere', which literally translates to 'to make an odor'. It combines 'olere' (to smell or emit a scent) with 'facere' (to make or do), highlighting the active biological process of capturing and identifying scent molecules.

Fun facts
