If an Ex or Cop is grammatically unique, i.e., lacks criterial features of any major word class in the language, it will tend to have a grammatically unique negative, i.e., the negative will not be formed the way other negatives in the language are formed.
Standardized
IF the lexical items for existential or copulative function form a word class of their own, THEN its negative will be distinct from other negatives.
