Add to ORKGI discuss a cleft-like construction found in various Slavonic languages, and argue that it should be analysed as containing a ‘double-IP ’ structure, and that the demonstrative pronominal èto/to appears in the specifier of the higher IP. The construction is a whole is, I claim, interpreted like an equative copular sentence. I show that this captures some properties which suggest a monoclausal structure (absence of lexical evidence for biclausality; restrictions on adverbials; clitic-climbing), as well as those which seem to favour a biclausal structure (presuppositions; Superiority in multiple wh-questions)
