This paper aims to provide an explanation of the lexical characterisation and final semantic interpretation associated with isolated argumental n-words in Question-Answer pairs in Negative Concord languages, namely Catalan and Spanish. We argue that there are two competing lexical variants of n-words in these languages: a polarity variant and a negative existential quantifier variant. Accessibility to these two lexical characterizations of n-words is correlated with one of the two possible final interpretations of isolated argumental n-words when used as fragment answers to negative wh-questions. Following a Structured Meaning approach to the semantics of Question-Answer pairs, we present a new analysis of n-words as focus constituents with respect to background wh-questions according to which a final single negation reading can only be inferred from n-words conceived as indefinite polarity items, whereas a Double Negation reading is inferred from negative quantifiers.
