CV2 is the abbreviation that is used for the construction featuring a clause introduced by a Complementiser (C) followed by Verb-Second (V2). CV2s are not syntactically integrated in the superordinate clause in which they are found, so they are unintegrated (U). Correspondingly, we will henceforth refer to CV2s as UCV2s, while noting that ICV2s (Integrated CV2s) are not found in Frisian.

The degree and effect construction is a construction which is semantically clear-cut, at least intuitively: it involves ascribing an effect to a degree. The semantic complement to the degree may be formally expressed: as a Verb-Final clause, as a Verb-Second clause, as a Verb-First clause.
