    - olfactory    
- olfactory: [17] Olfactory means etymologically ‘making smell’. It was borrowed from Latin *olfactōrius, a derivative of the verb olfacere ‘smell’. This in turn was a blend of olēre ‘smell’ (source of English redolent and related to odour) and facere ‘make’ (source of English fact, faction, etc).
 => odour, redolent
- olfactory (adj.)    
- 1650s, from Latin olfactorius, from olfact-, past participle stem of olfacere "to get the smell of, sniff," from olere "emit a smell, give off a smell of" (see odor) + facere "to make" (see factitious).
