Why can I hope to find out what is going on be followed by what can be added directly?Shouldn't object clauses have subject-verbs?How only predicates.
in sentences"i hope to find out what is going on"Medium,"what is going on"It is a noun clause. A noun clause plays the role of a noun in a sentence and can be the object of a subject, object, or preposition.
In this example sentence,"what is going on"is the whole noun clause that acts as the whole object. The clause itself already contains a complete subject (what) and predicate (is going on).
In a noun clause, the subject and predicate are already included in the clause, so there is no need for an additional subject. In this case, there is already a complete structure in the clause and there is no need to additionally add the subject. The noun clause itself already has a subject-verb relation, so there is no need to introduce another subject, because what already acts as the subject in the noun clause and is going on as the predicate part.
