From nux (“nut”) + -unculus (diminutive suffix).
This word is a hapax legomenon that is only attested in a table of Tironian notes (shorthand abbreviations). Because of this, we do not know in what context it was used, and therefore do not know its exact meaning. According to Lewis and Short, it might refer to a type of nut-cake (compare lucunculus かつ lībācunculus).
Second-declension noun.
