There are three types of ambiguity which have prompted me to write this paper; scope ambiguity, metarepresentational ambiguity, and presupposition preservation or cancellation. To better understand these ambiguities, I try to provide examples for each of them, along with my initial intuitions on how one can approach to avoiding them. However, to better understand why these ambiguities arise, one must delve deeper into the basic tenants of negation; its semantics and pragmatics. In this paper, I try to outline four approaches to the semantics and pragmatics of negation, based on Robyn Carston’s Thoughts and Utterances. These approaches can be categorized as those of semantic ambiguity with pragmatic disambiguation, and those of semantic univocality with pragmatics still playing a major role in the understanding of negation. The scope distinction is highly relevant for the understanding of these approaches, as the ones of semantic univocality diverge precisely in this aspect; some of them take the narrow scope of negation to be pragmatically derived from the wide scope, while others propose that neither is derived from the other, but rather from a different starting point altogether.
