In this chapter, I turn to Type I-CPs – that is, those CPs which have morphologically (and often semantically) related simple verbs that either show a strong increase in terms of their normalized frequencies or which have consistently very high frequencies of occurrence. I first test Hypothesis 1, stating that there is a correlation between the semantic scope and evolution of the CPs and that of their morphologically and semantically related simple verbs. The first analysis compares CPs with a semantic overlap to those without, asking whether both types confirm the hypothesis of a correlation between the semantic scope and evolution of the simple verb and that of the CP. Subsequently, I move on to explore which types of specialization apply to those CPs which have morphologically and semantically related CPs. I here look at changes in the modifier slot (Section 6.2), changes in the determiner slot (Section 6.3) and changes in the wider assertive and non-assertive contexts that these CPs occur in (Section 6.4). Finally, I ask whether the data analyzed allow us to make predictions as to which CPs specialize in which ways (Section 6.5).
