There exist in the language negative indefinites which preclude clausal negation. For example, in English, <i>nobody</i> is a negative indefinite which precludes clausal negation, as in <i>Nobody (*didn’t) left</i>, or <i>I (*don’t) see nobody</i> (see Haspelmath 2008).

Note:</b> Languages which use bipartite negation will be marked <b>N/A</b> for this property. There is a corresponding property for bipartite negation.
