This study, conducted by researchers of Sm’algyax, investigates the formation of polar questions (PolQs) and wh-questions (WhQs) in this Maritime Tsimshianic language, revealing a bipartite structure in main clauses that distinguishes them from embedded clauses. The research highlights the presence of two morphological markers in main-clause questions—specifically, the left-edge element “ał” and the polar-interrogative clitic “=ii”—while embedded questions are marked by a single complementizer, “dzi,” and lack the clitics.

The methodology involved eliciting data from fluent speakers through semantic fieldwork, focusing on the syntactic distribution of these interrogative elements. The findings indicate that the interrogative clitics are restricted to main clauses, suggesting a two-layer syntax that includes a clause-typing projection and a speech act projection. This contrasts with previous analyses that did not account for the unembeddability of certain speech act markers in embedded contexts.

The implications of this research are significant for understanding the typology of interrogative particles and the syntactic structures of questions across languages. It contributes to ongoing debates regarding the embedding of speech acts, suggesting that certain layers of syntax are not amenable to embedding, thereby refining theoretical frameworks within linguistics and communication science.
