ИСТИНА

Verb-Second orders arise in communicatively marked Slavic sentences and are triggered by Barrier rules. Verb-Second orders involve both clitic movement and verb movement. Initial topical Barriers are blocked in Bulgarian main clauses since this language has grammaticalized verb-and-clitic adjacency in sentences with the basic word order. Bulgarian VA-clitics are strong 2P clitics: they do not leave 2P and do not make this position available for verbal forms, which blocks for derived structures with verb movement. Common Slavic clitics are weak 2P clitics, they move out of clausal 2P and attract verbal forms to it, which triggers the verb-second & clitic-third order XP [V - CL] in communicatively marked sentences.
