Clauses
In grammar, a clause is the smallest grammar unit that can express a complete proposition. A typical clause consists of a subject and a predicate, where the predicate is typically a verb phrase – a verb together with any objects and other modifiers. However the subject is sometimes not expressed; this is often the case in null-subject languages, if the subject is retrievable from context, but it also occurs in certain cases in other languages such as English (as in imperative sentences and non-finite clauses).
A simple sentence usually consists of a single finite clause with a finite verb that is independent. More complex sentences may contain multiple clauses. Main clauses (= matrix clauses, independent clauses) are those that could stand as a sentence by themselves. Subordinate clauses (= embedded clauses, dependent clauses) are those that would be awkward or nonsensical if used alone.
Independent Clauses
An independent clause (or main clause) is a clause that can stand by itself, also known as a simple sentence. An independent clause contains a subject and a predicate; it makes sense by itself.
Independent clauses can be joined by using a semicolon or a coordinating conjunction (for, and, nor, but, or, yet, so).
Denpendent Clauses
A dependent clause (or a subordinate clause) is a clause that augments an independent clause with additional information, but which cannot stand alone as a sentence. Dependent clauses either modify the independent clause of a sentence or serve as a component of it. Some grammarians use the term subordinate clause as a synonym for dependent clause. Other grammars use subordinate clause to refer only to adverbial dependent clauses. There are also different types of dependent clauses, including noun clauses, relative (adjectival) clauses, and adverbial clauses.
Dependent clauses often begin with a a subordinating conjunction or relative pronoun (see below) that makes the clause unable to stand alone.
For example:
The door opened because the man pushed it.
Dependent clauses can be nominal, adverbial or adjectival.
A nominal clause (noun clause) functions like a noun or noun phrase. It is a group of words containing a subject and a finite verb of its own and contains one of the following: that | if | whether
For example:
An adverbial clause (adverb clause) is a word or expression in the sentence that functions as an adverb; that is, it tells you something about how the action in the verb was done. An adverbial clause is separated from the other clauses by any of the following subordinating conjunctions: after | although | as | because | before | if | since | that | though | till | unless | until | when | where | while
For example:
For example:
Adverb clauses answer questions like "when?", "where?", "why?"
An adjectival clause (adjective clause or relative clause) does the work of an adjective and describes a noun, it's usually introduced by a relative pronoun: who | whom | whose | that | which
For example:
For example:
For example:
!Note - The difference between a clause and a phrase is that a phrase does not contain a finite verb.
Who(m) is used when the antecedent is a person.
That is used to refer to either a person or thing.
Which is used to refer to anything exept a person.
In English a non-restrictive relative clause is preceded by a pause in speech or a comma in writing, unlike a restrictive clause.
For example:-
This second example uses a restrictive relative clause. Without the commas, the sentence states that any builder who builds such houses will make a profit.

Dependent clauses can be nominal, adverbial or adjectival.
A nominal clause (noun clause) functions like a noun or noun phrase. It is a group of words containing a subject and a finite verb of its own and contains one of the following: that | if | whether
For example:
- I wondered whether the homework was necessary.
An adverbial clause (adverb clause) is a word or expression in the sentence that functions as an adverb; that is, it tells you something about how the action in the verb was done. An adverbial clause is separated from the other clauses by any of the following subordinating conjunctions: after | although | as | because | before | if | since | that | though | till | unless | until | when | where | while
For example:
- They will visit you before they go to the airport.
For example:
- Before they go to the airport, they will visit you.
Adverb clauses answer questions like "when?", "where?", "why?"
An adjectival clause (adjective clause or relative clause) does the work of an adjective and describes a noun, it's usually introduced by a relative pronoun: who | whom | whose | that | which
For example:
- I went to the show that was very popular.
For example:
- The car that is parked in front of the gates will be towed away. (Defining relative clause.)
- My dog, who is grey and white, chased the postman. ( Non-defining relative clause)
For example:
- My dog chased the postman.
Summary
An adjective clause functions as an adjective (modifies a noun or pronoun); an adverb clause functions as an adverb (describes a verb, adjective or other adverb); a noun clause is used as a noun (subject of a verb, direct object, indirect object, predicate nominative or object of the preposition).!Note - The difference between a clause and a phrase is that a phrase does not contain a finite verb.
Relative Clauses
A relative clause follows the noun it modifies. It is generally indicated by a relative pronoun at the start of the clause, although sometimes you can tell simply by word order. The choice of relative pronoun, or choice to omit one, can be affected by the following:-Human or Non-human?
We make a distinction between an antecedent that is a human — who(m) — and an antecedent which is a non-human — which.Who(m) is used when the antecedent is a person.
That is used to refer to either a person or thing.
Which is used to refer to anything exept a person.
- I met a man and a woman yesterday. The woman, who had long blonde hair, was very pretty.
- The man she was with, was the man that / who won the race.
- The race was the one that I lost.
- The man, to whom the winnings were given, was with the woman who was very pretty.
Restrictive or Non-restrictive?
Restrictive relative clauses are sometimes called defining relative clauses, or identifying relative clauses. Similarly, non-restrictive relative clauses are called non-defining or non-identifying relative clauses.In English a non-restrictive relative clause is preceded by a pause in speech or a comma in writing, unlike a restrictive clause.
For example:-
- The builder, who erects very fine houses, will make a large profit.
This example, with commas, contains a non-restrictive relative clause. It refers to a specific builder, and assumes we know which builder is intended. It tells us firstly about his houses, then about his profits.
This second example uses a restrictive relative clause. Without the commas, the sentence states that any builder who builds such houses will make a profit.
Restrictive | Non-restrictive | |||
---|---|---|---|---|
Human | Nonhuman | Human | Nonhuman | |
Subject | who, that | which, that | who | which |
Object | who, whom, that, Ø | which, that, Ø | who, whom | which |
After preposition | whom | which | whom | which |
Possessive | whose, of whom | whose, of which | whose, of whom | whose, of which |

Passive Voice Exercises
PASSIVE VOICE AND THE NEWS
THE PASSIVE VOICE IS GENERALLY USED TO TALK ABOUT THE NEWS ON RADIO, TELEVISION AND IN THE NEWSPAPERS.
PUT
THESE TEXTS INTO THE PASSIVE: Remember to use capital letters at the
beginning of each sentence, a stop sign (.) at the end and to use the
correct apostrophe (') sign".
Remember also that intransitive verbs (arrive, go...) cannot be put into passive, so some verbs will remain active.
TEXT 1:
Some people saw a UFO in the sky above Madrid last Tuesday. They reported it to the police. The army sent a helicopter to have a closer look. The UFO shot the helicopter down and killed the pilot. Some young people have given photographs of the UFO to the police. Experts are investigating them at the moment.
TEXT 2:
Somebody has stolen a lady's bag near a high-school this afternoon. The students saw the robber and told the police. They are looking for him now. They will use the children’s descriptions to catch the man as soon as possible.
TEXT 3:
Someone broke into a clothes shop last week. The owner was locking up the shop when a robber with a gun threatened her. The robber told her to open the door and give him all the money from the till. Then the robber tied the woman up. The police hope they will find him in a few days. Doctors are treating the owner of the shop for shock at the local hospital.
TEXT 4:
Our school has organised a contest. Any student can participate. You have to design an environmental friendly object. All the pupils will vote and they will choose the best idea. The participants can also include pictures and drawings. The school doesn't allow any adult to help the students with the projects. The school will give the winner a set of books about nature.
Write a news report in the Passive using the notes below.
A small German village- flod- intense rains - last night. Fortunately many people - can- rescue. However, most houses - destroy- the force of the water. Soldiers -already- send- to the village. The local sports centre- be used - as temporary shelter - for those who - lose their houses. Efforts- still- make to clear the village. Clean water, food and blankets- send- nearby countries in the next few days. Heavy rains -also- predict- next week. Any further news- give- to you as soon as it arrives.

Reported Speech Grammar Part II
Place, demonstratives and time expressions
Place, demonstratives and time expressions change if the context of the reported statement (i.e. the location and/or the period of time) is different from that of the direct speech.
In the following table, you will find the different changes of place; demonstratives and time expressions.
Direct Speech | Reported Speech |
---|---|
Time Expressions | |
today | that day |
now | then |
yesterday | the day before |
… days ago | … days before |
last week | the week before |
next year | the following year |
tomorrow | the next day / the following day |
Place | |
here | there |
Demonstratives | |
this | that |
these | those |
B. Reporting Questions
When transforming questions, check whether you have to change:
Also note that you have to:
- pronouns
- place and time expressions
- tenses (backshift)
- transform the question into an indirect question
- use the question word (where, when, what, how) or if / whether
Types of questions Direct speech Reported speech With question word (what, why, where, how...) "Why" don’t you speak English?” He asked me why I didn’t speak English. Without question word (yes or no questions) “Do you speak English?” He asked me whether / if I spoke English.
C. Reporting requests / commands
When transforming requests and commands, check whether you have to change:
- pronouns
- place and time expressions
Direct speech | Reported speech |
---|---|
“Nancy,do the exercise.“ | He told Nancy to do the exercise. |
"Nancy, give me your pen, please." | He asked Nancy to give him her pen. |
Tenses are not relevant for requests – simply use to / not to + verb (infinitive without "to") |
Example:
She said, “Sit down." - She asked me to sit down.
She said, "don't be lazy" - She asked me not to be lazy
For affirmative use to + infinitive (without to)
For negative requests, use not to + infinitive (without to).
|
D. Other transformations
- Expressions of advice with must, should and ought are usually reported using advise / urge.
Example:
“You must read this book.“
He advised / urged me to read that book.- The expression let’s is usually reported using suggest. In this case, there are two possibilities for reported speech: gerund or statement with should.
Example:
“Let’s go to the cinema.“=
1. He suggested going to the cinema.
2. He suggested that we should go to the cinema.

Reported Speech
Indirect speech, also called reported speech or indirect discourse, is a means of expressing the content of statements, questions or other utterances, without quoting them explicitly as is done in direct speech. For example, He said "I'm coming" is direct speech, whereas He said he was coming is indirect speech. Indirect speech should not be confused with indirect speech acts.
In terms of grammar, indirect speech often makes use of certain syntactic structures such as content clauses ("that" clauses, such as (that) he was coming), and sometimes infinitive phrases. References to questions in indirect speech frequently take the form of interrogative content clauses, also called indirect questions (such as whether he was coming).
In indirect speech certain grammatical categories are changed relative to the words of the original sentence. For example, person may change as a result of a change of speaker or listener (as I changes to he in the example above). In some languages, including English, the tense of verbs is often changed – this is often called sequence of tenses. Some languages have a change of mood: Latin switches from indicative to the infinitive (for statements) or the subjunctive (for questions).
When written, indirect speech is not normally enclosed in quotation marks or any similar typographical devices for indicating that a direct quotation is being made. However such devices are sometimes used to indicate that the indirect speech is a faithful quotation of someone's words (with additional devices such as square brackets and ellipses to indicate deviations or omissions from those words), as in He informed us that "after dinner [he] would like to make an announcement".

problems for native and non-native speakers of English. Sometimes you
can use either one and sometimes you have to choose either one or the
other, but neither one is very difficult.
