olfactory

The word 'olfactory' is a direct borrowing from Latin olfactorius, which itself derives from the verb olfacere, meaning 'to smell'. Olfacere is a compound of olēre ('to give off a smell') and facere ('to make, do'), literally translating to 'to make a smell' or 'to perceive a smell'. This Latin root passed into scientific English in the 17th century to specifically describe the anatomical and sensory apparatus related to smell. Thus, the modern term retains its literal connection to the act of smelling, now applied in a technical and biological context.

Structure: olfact (to smell) + ory (relating to) - olfact: From Latin olfactus, the past participle of olfacere meaning 'to smell'. It serves as the core root conveying the sense of smell. - ory: A suffix of Latin origin (-orius) used to form adjectives meaning 'pertaining to, serving for, or characterized by'.
