This paper provides insight into the phenomenon of extra negation, also known as non-compositional, expletive, or
pleonastic negation. It provides a corpus-based analysis of the Dutch negative privative construction, which consists of
zonder ‘without’ and niet ‘not’, in which one negation does not cancel the other. Two basic
factors that trigger an extra negation are discussed, and an explanation of why these factors facilitate the use of an extra
negation is offered. It is argued that the extra negation has a semantic-pragmatic function that is reminiscent of similar
instances of extra negation in Dutch and other languages, specifically sentences consisting of a main clause and a subordinate
clause containing a word which expresses implicit negation. It is shown that in complex hypotactic constructions, the extra
negation is used to make explicit in the subordinate clause that the presupposition of non-occurrence is rejected.
