Negation in LIS is mainly conveyed through negative markers and n-words (SYNTAX 1.5.1.1) whose syntactic features are analysed in SYNTAX 1.5.1.2. However, there are some instances of negation as inflectional category, which will be explored in the next sections. Negation as inflectional category refers to the morphological modifications that predicates or sentences can undergo in order to convey negation, besides employing lexical negative markers. Specifically, LIS verbs can i) incorporate negative elements, ii) be marked by specific non-manual markers or iii) display a completely different form to convey their negative counterpart.
