ABSTRACT
In this chapter I investigate the conditions that render the use of parametric cái, jiù, dōu and yĕ obligatory or impossible as long as we keep the semantic nature of the foci involved constant and appropriate. (See ch. 4 for discussion of the relevant focus-semantic aspects.) By and large, we will be dealing with facts of relative position and movement. The relative position of cái, jiù, dōu and yĕ with regard to interacting foci is important because it is, with only few exceptions in cái-sentences, impossible for a focus interacting with a parametric word to follow that word. Movement of canonically post-verbal elements may ensure the required relative position of foci and parametric words in single cases, and therefore, some movement facts are discussed.
