Negative verb

Dryer defined three different types of negative markers in language. Beside negative particles and negative affixes, negative verbs play a role in various languages. The negative verb is used to implement a clausal negation. The negative predicate counts as a semantic function and is localized and therefore grammaticalized in different languages. Negation verbs are often used as an auxiliary type which also carries φ-feature content. This could be visualized for example in the inflectional character of the negation verb while combined with the main verb. Dryer observes a tendency to place the negation verb before the finite verb. Miestamo researched four different types of negations and proposed a distinction between symmetric negation in which a negative marker is added and asymmetric negation in which, beside the added negation marker, other structural changes appear.
