Reconstruction:Proto-Indo-European/nókʷts

Etymology
Pooth argues that the word derives from, and that the ablaut variants should be analyzed as two separate words,  and , root nouns meaning "dusk" and "night" respectively, or originally "getting bare (of sunlight)" (action noun) and "the result of getting bare (of sunlight)" (noun with detransitive or middle meaning marked by the vowel ). This analysis differs from the traditional one, in which are simply ablaut variants used in different parts of the nominal paradigm, with no difference in meaning.

Kloekhorst cites Kroonen that is from  and assumes the initial was dropped "at an early stage".
