Mismatch between syntax and prosody and complex sentence structure in Hittite

Hittite attests a set of complex sentences in which (mostly) relative clauses (other subordinate clauses are also attested) appear in linear syntax to be within another subordinate (usually conditional, rarely temporal) clause or main clause. The relative clause can be preceded by a very limited array of constituents from the matrix clause, e.g., mān ‘if’ or the quotative particle ⸗wa(r). There are also examples which attest the conditional subordinator and the irrealis particle in two positions simultaneously, at the left edge of the whole sentence and in the conditional clause (= main clause for the relative clause). I provide a fine-grained descriptive and structural analysis of the structure and show that the type cannot be explained as bare indefinites, embedded relative clauses or parenthetic clauses. It is shown that, structurally, the sentences containing subordinate (mostly relative) clauses within other clauses are heterogenous and of three types. The difference lies in the elements that precede the relative clause and in the structure of the sentences, whereby a standard Hittite relative clause adjoins at different heights. All three types display the same mismatch between prosodic domains and syntax/semantics—the constituent that is part of the main clause from the semantic and syntactic perspective is prosodically part of the relative clause. Since there is a clause boundary delimiting the end of the subordinate clause within the main clause, it makes sense to treat the surface structure as a distinct taxonomic unit, which is correspondingly labelled a mismatch sentence. The new evidence allows us to obtain a fuller understanding of the Hittite left periphery than was previously possible. It thus offers an important window into hitherto unrecognized aspects of the underlying structure of the complex sentence in Hittite.
