coherence and cohesion
If you write more than one or two sentences on a subject, you have to ensure that your text holds together and makes sense to your readers. You do this by making sure that it has two important qualities:
■ coherence
■ cohesion
Coherence
Coherence means that the thought behind the text is consistent and moves logically from one point to the next. A coherent text uses suitable vocabulary and uses it consistently.
Cohesion
The use of grammatical devices to make sure that a text sticks together. The commonest of these are:
■ reference
■ ellipsis
■ sentence adverbials
