10.96 Introducing your statement: prefacing structures

People often use structures which point forward to what they are going to say and classify or label it in some way. These are called prefacing structures or prefaces.

A preface usually introduces the second part of the same sentence, usually a 'that'-clause or a 'wh'-clause, but occasionally a non-finite clause or a noun group. However, you can also use a whole sentence as the preface to another sentence (see paragraph 10.101).
