What you did last summer. That’s a noun clause.

Clause and phrase are parts of a sentence. A clause is a group of words that consists of a subject and a verb. Examples: A phrase is a group of words that does not consist of a subject and a verb. Examples: on a table, under the tree, near the wall, on the roof, at the door.

Clauses come in four types: main (or independent), subordinate (or dependent), adjective (or relative), and noun. Every clause has at least one subject and one verb. Other characteristics will help you distinguish one type of clause from another.

In grammar a clause is a group of words that contains a subject and verb. All sentences are clauses, but not all clauses are sentences. There are also dependent clauses, which do not express a complete thought and are not sentences. …

DEFINITION OF CLAUSE AND PHRASE: A clause is a group of words with a subject-verb unit; the 2nd group of words contains the subject-verb unit the bus goes, so it is a clause. A phrase is a group of words without a subject-verb unit. It has no verb, so it can’t have a subject-verb unit.

Non-defining clauses still add extra information, but not in the same way. While they tell you something additional, they’re not necessary to the meaning of the sentence, but just add an extra non-essential dimension. The only difference is that you cannot use “that” with a non-defining clause, unlike defining clauses.

A non-defining relative clause is not essential in a sentence because it just adds more information about who or what we are describing, therefore you could leave it out of the sentence and the sentence would still make sense and it would still be clear who or what we are describing.

Non-defining relative clauses (also known as non-restrictive, or parenthetical, clauses) provide some additional information that is not essential and may be omitted without affecting the contents of the sentence.

We always use a relative pronoun or adverb to start a non-defining relative clause: who, which, whose, when or where (but not that). We also use commas to separate the clause from the rest of the sentence.

Non-restrictive (non-defining) relative clauses can be reduced in one way; subject pronouns with “be” verbs can be deleted.

Relative clauses add extra information to a sentence by defining a noun. Defining relative clauses add essential information to a sentence and the clause cannot be omitted. Non-defining relative clauses add non-essential information to a sentence and can be left out of a sentence without changing it’s meaning.

We can’t drop the relative pronoun. For example (clause after the object of the sentence):…

• The bike (which / that) I loved was stolen.
• The university (which / that) she likes is famous.
• The woman (who / that) my brother loves is from Mexico.
• The doctor (who / that) my grandmother liked lives in New York.

A defining relative clause identifies who or what we are speaking about, whereas a non-defining relative clause just gives us more information about who or what we are speaking about. A defining relative clause is essential in a sentence because we need it in order to know who or what someone is describing.

Reduced relative clauses refer to the shortening of a relative clause which modifies the subject of a sentence. Reduced relative clauses modify the subject and not the object of a sentence….Reduce to a Past Participle

1. Remove the relative pronoun.
2. Remove the verb “be.”
3. Place the past participle before the modified noun.

However, there is equilibrium everywhere: in sentences that have subject relative clauses, you can’t omit the relative pronoun, but you can reduce clauses to phrases. We can do this by omitting the subject pronoun and the form of “to be” that follows it.

What is a relative clause? A relative clause is one kind of dependent clause. It has a subject and verb, but can’t stand alone as a sentence. It is sometimes called an “adjective clause” because it functions like an adjective—it gives more information about a noun.
