|4. Noun Clause|
A noun clause is a group of words that include a subject and a verb, and it functions as a noun. A noun clause is a subordinate clause, which means it is not a complete statement. As a dependent clause, it must connect to an independent clause (main clause). Noun clauses usually begin with words such as how, that, what, whatever, when, where, which, who, whoever, and why. The most common word among them is that.

Noun clauses can be the subject, object, object of preposition, complement, etc. The noun clauses in the following examples are in bold.
A noun clause has its own subject and verb.
A noun clause must have a word to connect the noun clause to the rest of the sentence. The connecting word (connector) comes before the subject and the verb of the noun clause. The following examples use the connecting words that, who, and when.
Subjunctive in noun clauses
We use subjective verbs in sentences to express or stress wishes, importance, or urgency. A subjunctive verb usually appears in a noun clause beginning with that, and it uses the simple form of a verb that does not have the present, past or future forms. The subjunctive verb is neither singular nor plural.
