ABSTRACT
The relation between the clauses is one of hypotaxis where one clause is dominant over the other on which it is bound. The ways of distinguishing one type of bound clause from another are: semantics, syntax and componence. Contingent-clause binders functions simultaneously as binder and as adjunct within their clause. It's modifies limits the proposition of the dominant clause and they are the important group of contingencies that are given the collective name conditional which is reserved for the if-type clause. Clause sequences of adding clauses are given in the BF sequence which is impossible with adding clauses. P-bound adding clauses have no binder where the syntactic relation to these words in the dominant clause, is the same as in the type of adding clause. The adding clause supplies extra information, separate from the dominant clause proposition. The presence of the bound clause is optional; the structure of the dominant clause is not disturbed if the contingent clause is removed.
