ABSTRACT
As already mentioned in the introduction to chapter 2, although it is generally agreed that sentences have a less informative or more topical part, and a more informative or less topical part, there has been no agreement as to the point and nature of this split. We have already considered the problems of identifying a topic and the different notions available in the literature, and we have proposed that two different topical elements should be distinguished. Now, we turn to the notion of focus.
