Etymology

De Vaan tentatively reconstructs Proto-Italic *knei/īd-os- and Proto-Indo-European *knei(H)d-os- (“itch”), assuming that a strong smell was named from a verb “to itch, sting”; on this view it is related to Ancient Greek κνῖσα (knîsa, “smell of roasting fat”), Ancient Greek κνίζω (knízō, “to scratch”), Old Norse hniss (“cooking smell”) and Latvian knìest (“to itch”), but the vowels are hard to reconcile.[2] The OLD compares the Greek and Old Norse words.[3]

Earliest recorded meaning

Köbler dates it from Plautus,[4] who calls a slave who is always in the kitchen nidor e culina, “a whiff from the kitchen”, in the Mostellaria.[5] Plautus also has nīdōricupius, “fond of the smell of cooking”.[2]

Semantic evolution

It is a rich, strong smell from cooking or burning, and loosely any strong smell.[3] Lucretius has a lamp just put out offending the nostrils with its sharp smell, Cicero the fumes and smoke of cookshops, and Livy a foul smell from burnt feathers.[5] Virgil has the smoke of burning galbanum, and Martial and Juvenal the smell of the kitchen.[5]
