* Some of the categories represented here probably do not exist. Can, for example, a predicate noun clause be located to the left (before) the verb to which it functions as the predicate noun? Because, however, this table is intended to reflect research, much of which has not yet been done, I have followed the example of Levi-Strauss by creating a matrix of all theoretically possible cases. Delayed subjects are represented only once because by their very definition they are delayed, i.e., to the right of the finite verb.
