A family of non-standard relatives

Extraposed relative clauses from definite DPs (see: Kupferman 2016) and predicate relative clauses show up as exhibiting a large array of similar distinctive properties, but, moreover, they enter also into a major set of syntactic and interpretative constructions. All those relative clauses denote scenes which take place under a non agentive perception. Verbal or nominal items governing these relative clauses appear as predicates which function as setting factors of those scenes over the particular situation. Therefore, such a complex-sentence should be analyzed over two levels : an argument structure of secondary predication, and a syntactic structure, where the secondary predicate is projected as a (non standard) relative clause and the secondary argument is projected as an object DP of the primary VP. In a string formed by 1) an external head DP and 2) a non standard relative clause, 2) functions as a predicate, and 1) as its argument in a secondary predication mechanism. The submitted analysis wishes to overcome a more traditional description of the particular case of the predicative relative clauses, according to which they ought to be derived from complement clauses, where the complemetizer is converted into a subject qui.
