Answer: I heard that trucks can no longer travel on Grove Street. (N noun)
A clause is formed by a Subject + Verb. We know that clauses can be independent (they can stand alone) or dependent (they can't stand alone).
Dependent clauses can be classified into:
- ADV - Adverbial clauses: these are dependent clauses that act as an adverb, modifying a verb, an adjective or another adverb. In general, they make reference to when, where, why, how, how much, or under what circumstance the action takes place, e.g "Before we go to my mother's house, we should buy her a present"
- ADJ - Adjectival clauses: these are dependent clauses that act as an adjective, describing a noun in a sentence. In this way, they modify the noun. The head of these clauses is a relative pronoun, which links them to the word they describe: that, where, when, who, whose, whom, which, why, e.g "My father is the man who sold you the car"
- N - Noun clauses: these are also dependent clauses, and they act as a noun. They may be the subject of a sentence, direct or indirect object, object of a preposition or predicate nominative. Noun clauses begin with words like that, how, what, whatever, where, when, whether, which, whichever, who, whoever, whom, whomever, and why.
A good technique to identify noun clauses is to replace them by the word "this or that".
Example: "I heard that trucks can no longer travel on Grove Street."
"I heard this."
