Connectives - VerbindingswoordenIntroductionCohesion can be achieved by making use of connectives which establish a link between two elements. The nature of the link determines the kind of connective you use. Thus, the first example below expresses a causal relationship between the sun shining and my taking the bike. The second example expresses a contrastive relationship between the weather conditions and my mode of transport.
The table below lists the mosty common relationships together with the connectives that are mosty commonly used to express these relationships.
Knowing how to correctly use these connectives is very important. In order to use them successfully you not only need to know their meaning (i.e. the semantic relation they express), but you must also know what effect the use of connectives has on the construction of your text. Therefore, the connectives in the above list are subdivided below into three categories, depending on the syntactic connection that is made by them:
