Sentential Complement: Tnx0Vs1

Description:

This tree family is selected by verbs that take just a sentential complement. The sentential complement may be of type infinitive, indicative, or small clause (see Chapter 9). The type of clause is specified by each individual verb in its syntactic lexicon entry, and a given verb may select more than one type of sentential complement. The declarative tree, and many other trees in this family, are auxiliary trees, as opposed to the more common initial trees. These auxiliary trees adjoin onto an S node in an existing tree of the type specified by the sentential complement. This is the mechanism by which TAGs are able to maintain long-distance dependencies (see Chapter 13), even over multiple embeddings (e.g. What did Bill think that John said?). 338 verbs select this tree family.

Examples:

consider, think
Dania considered the algorithm unworkable .
Srini thought that the program was working .

Declarative tree:

See Figure 6.12.
