In chapter 9 (pp. 169 ff.) we have seen that connectors and anaphoric constituents often occur at or near the beginning of the sentence. The same
holds for constituents that are known from the preceding context (or for some other reason) and, therefore, qualify for the pragmatic function Topic. In this way, they serve as an anchor for new information. Furthermore, constituents that are constrasted with something in the preceding context are often placed at the beginning of the sentence. In crosssection 12.1. I have shown that Theme constituents in the first position of the sentence are sometimes used to introduce a new element in the discourse (a new `episode'). Presentative sentences, too, often have this function. The order of the constituents in a sentence is, therefore, to a large extent determined by language users' desire to make clear how such a sentence is related to what preceded.
