infinitive clause

An infinitive clause may be the object of the preposition for.

When it is possible, substitute a that-clause for the infinitive clause.

The infinitive clause is, therefore, a peculiar exception, for him to go makes an assertion as clearly as that he should go does.

A predicate pronoun after to be in an infinitive clause is in the objective case, agreeing with the subject of the infinitive.

An infinitive clause with for may be used as a subject, as a predicate nominative, or as the object of a preposition.
