negasjonen

Negasjonen, or negation, is the semantic and syntactic operation that denies, contradicts, or reverses the truth of a proposition. In logic, negation is a unary connective that maps a proposition p to ¬p, flipping its truth value. In natural language, negation is realized by linguistic elements known as negators, such as not or ikke, depending on the language. The position and scope of negation can affect the truth-conditions of clauses; it commonly appears before the predicate, but can be distributed or split across auxiliary verbs in complex sentences.

Languages employ a variety of strategies for negation. Some rely on separate negation words (not, ikke, non),

In semantics and pragmatics, negation interacts with polarity items and scope-taking operators, influencing inference and discourse
