Then the concepts of semi-dependent clause, parenthesis and relational modality are delimited. The core of the article is a classification of semi-dependent and parenthetic clauses, the juxtaposition of declarative clauses and the juxtaposition of clauses of different relational modality in. compound-complex super-clausal units.
