On Dynamic Textual Functions of English Disjuncts

Traditionally, studies on disjuncts have been carried solely on the syntactic level, thinking that disjuncts have only commentary function and are optional elements in sentences. It is observed that disjuncts play a very important role in constructing a coherent text and can not be replaced or neglected. It can make the readers feel at ease to co-operate with the writer in constructing a coherent text. The creation of a context is actually a negotiation between the writer and the reader, involving their choices from a potential large amount of language resources. Disjuncts enable the writer to negotiate with his readers, therefore they are important cohesive devices and are dynamic cohesive pivots between contextual propositions, having an important significance in constructing a cohesive and coherent text.
