sindiotàctica
Sindiotàctica refers to a grammatical construction in which a subordinate clause is introduced by a conjunction that normally serves to introduce a coordinate clause. This often occurs with the conjunction "que" (that) in Spanish, where it can introduce either a subordinate or a coordinate clause depending on the context. The term is derived from the Greek words "syn" (together) and "diá" (through) and "tasso" (to arrange or order). In essence, sindiotàctica involves a perceived joining of clauses where a more explicit subordination might be expected.
This phenomenon can be observed in various languages, though the specific conjunctions and their usage differ.
