From Proto-Celtic *knūs, cognate with Proto-Germanic *hnuts, Latin nux.
cnú f (genitive cnó, nominative plural cnói)
This noun is traditionally labelled as a one-of-a-kind "feminine u-stem" despite neither inflecting like a u-stem nor originating from one. Instead it inflects as a consonant stem noun resembling the declension of bó (“cow”) with several forms terminating in -i whose locations parallel those of palatalized auslaut consonants of the velar-stem declensions.
