The third conditional (also called conditional type 3) is a structure used for talking about unreal situations in the past. This page will explain how the third conditional is formed, and when to use it.

The structure of a third conditional sentence

Like the other conditionals, a third conditional sentence consists of two clauses, an "if" clause and a main clause:

If the "if" clause comes first, a comma is usually used. If the "if" clause comes second, there is no need for a comma:

We use different verb forms in each part of a third conditional:

*The past perfect is formed with the auxiliary verb "had", and the past participle (or third form) of the verb.

Note also that third conditional forms can be contracted:

Using the third conditional

The third conditional is used to talk about things which DID NOT HAPPEN in the past. If your native language does not have a similar construction, you may find this a little strange, but it can be very useful. It is often used to express criticism or regret:

Those of you who have been following the Conditional Tutorial should now be familiar with present, past and future conditional verb forms. Sometimes Unreal Conditional sentences are mixed. This means that the time in the if-clause is not the same as the time in the result. Study the examples below to learn how to mix conditional verb forms like a native speaker.

Verbs in green are in the Present Unreal Conditional.

Verbs in red are in the Past Unreal Conditional.

Verbs in purple are in the Future Unreal Conditional.

.  A phrasal verb is a verb plus a preposition or adverb which creates a meaning different from the original verb. Example:
I ran into my teacher at the movies last night. run + into = meet
He ran away when he was 15. run + away = leave home

2. Some phrasal verbs are intransitive. An intransitive verb cannot be followed by an object.

Example:
He suddenly showed up. "show up" cannot take an object

3. Some phrasal verbs are transitive. A transitive verb can be followed by an object.

Example:
I made up the story. "story" is the object of "make up"

4. Some transitive phrasal verbs are separable. The object is placed between the verb and the preposition. In this Phrasal Verb Dictionary, separable phrasal verbs are marked by placing a * between the verb and the preposition / adverb.

Example:
I talked my mother into letting me borrow the car.
She looked the phone number up.

5. Some transitive phrasal verbs are inseparable. The object is placed after the preposition. In this Phrasal Verb Dictionary, inseparable phrasal verbs are marked by placing a + after the preposition / adverb.

Example:
I ran into an old friend yesterday.
They are looking into the problem.

6. Some transitive phrasal verbs can take an object in both places. In this Phrasal Verb Dictionary, such phrasal verbs are marked with both * and + .

Example:
I looked the number up in the phone book.
I looked up the number in the phone book.

7. WARNING! Although many phrasal verbs can take an object in both places, you must put the object between the verb and the preposition if the object is a pronoun.

Example:
I looked the number up in the phone book.
I looked up the number in the phone book.
I looked it up in the phone book. correct
I looked up it in the phone book. incorrect

Past Perfect

FORM

[had + past participle]

Examples:

• You had studied English before you moved to New York.
• Had you studied English before you moved to New York?
• You had not studied English before you moved to New York.

Complete List of Past Perfect Forms

USE 1 Completed Action Before Something in the Past

The Past Perfect expresses the idea that something occurred before another action in the past. It can also show that something happened before a specific time in the past.

Examples:

• I had never seen such a beautiful beach before I went to Kauai.
• I did not have any money because I had lost my wallet.
• Tony knew Istanbul so well because he had visited the city several times.
• Had Susan ever studied Thai before she moved to Thailand?
• She only understood the movie because she had read the book.
• Kristine had never been to an opera before last night.
• We were not able to get a hotel room because we had not booked in advance.
• A: Had you ever visited the U.S. before your trip in 2006?
  B: Yes, I had been to the U.S. once before.

USE 2 Duration Before Something in the Past (Non-Continuous Verbs)

With Non-Continuous Verbs and some non-continuous uses of Mixed Verbs, we use the Past Perfect to show that something started in the past and continued up until another action in the past.

Examples:

• We had had that car for ten years before it broke down.
• By the time Alex finished his studies, he had been in London for over eight years.
• They felt bad about selling the house because they had owned it for more than forty years.

Although the above use of Past Perfect is normally limited to Non-Continuous Verbs and non-continuous uses of Mixed Verbs, the words "live," "work," "teach," and "study" are sometimes used in this way even though they are NOT Non-Continuous Verbs.

IMPORTANT Specific Times with the Past Perfect

Unlike with the Present Perfect, it is possible to use specific time words or phrases with the Past Perfect. Although this is possible, it is usually not necessary.

Example:

• She had visited her Japanese relatives once in 1993 before she moved in with them in 1996.

MOREOVER

If the Past Perfect action did occur at a specific time, the Simple Past can be used instead of the Past Perfect when "before" or "after" is used in the sentence. The words "before" and "after" actually tell you what happens first, so the Past Perfect is optional. For this reason, both sentences below are correct.

Examples:

• She had visited her Japanese relatives once in 1993 before she moved in with them in 1996.
• She visited her Japanese relatives once in 1993 before she moved in with them in 1996.

HOWEVER

If the Past Perfect is not referring to an action at a specific time, Past Perfect is not optional. Compare the examples below. Here Past Perfect is referring to a lack of experience rather than an action at a specific time. For this reason, Simple Past cannot be used.

Examples:

• She never saw a bear before she moved to Alaska. Not Correct
• She had never seen a bear before she moved to Alaska. Correct

ADVERB PLACEMENT

The examples below show the placement for grammar adverbs such as: always, only, never, ever, still, just, etc.

Examples:

• You had previously studied English before you moved to New York.
• Had you previously studied English before you moved to New York?

ACTIVE / PASSIVE

Examples:

• George had repaired many cars before he received his mechanic's license. Active
• Many cars had been repaired by George before he received his mechanic's license. Passive

Grammar Tenses Mix

Test your knowledge on grammar - English tenses (active and passive voice). After submitting your answers, you will see how well you have done in the test.

Use of Passive

Passive voice is used when the focus is on the action. It is not important or not known, however, who or what is performing the action.

Example: My bike was stolen.

In the example above, the focus is on the fact that my bike was stolen. I do not know, however, who did it.

Sometimes a statement in passive is more polite than active voice, as the following example shows:

Example: A mistake was made.

In this case, I focus on the fact that a mistake was made, but I do not blame anyone (e.g. You have made a mistake.).

Form of Passive

Subject + finite form of to be + Past Participle (3rd column of irregular verbs)

Example: A letter was written.

When rewriting active sentences in passive voice, note the following:

• the object of the active sentence becomes the subject of the passive sentence
• the finite form of the verb is changed (to be + past participle)
• the subject of the active sentence becomes the object of the passive sentence (or is dropped)

Examples of Passive Level: lower intermediate

Examples of Passive Level: upper intermediate

Passive Sentences with Two Objects

Rewriting an active sentence with two objects in passive voice means that one of the two objects becomes the subject, the other one remains an object. Which object to transform into a subject depends on what you want to put the focus on.

.

As you can see in the examples, adding by Rita does not sound very elegant. That's why it is usually dropped.

Personal and Impersonal Passive

Personal Passive simply means that the object of the active sentence becomes the subject of the passive sentence. So every verb that needs an object (transitive verb) can form a personal passive.

Example: They build houses. - Houses are built.

Verbs without an object (intransitive verb) normally cannot form a personal passive sentence (as there is no object that can become the subject of the passive sentence). If you want to use an intransitive verb in passive voice, you need an impersonal construction - therefore this passive is called Impersonal Passive.

Example: he says - it is said

Impersonal Passive is not as common in English as in some other languages (e.g. German, Latin). In English, Impersonal Passive is only possible with verbs of perception (e. g. say, think, know).

Example: They say that women live longer than men. - It is said that women live longer than men.

Although Impersonal Passive is possible here, Personal Passive is more common.

Example: They say that women live longer than men. - Women are said to live longer than men.

The subject of the subordinate clause (women) goes to the beginning of the sentence; the verb of perception is put into passive voice. The rest of the sentence is added using an infinitive construction with 'to' (certain auxiliary verbs and that are dropped).

Sometimes the term Personal Passive is used in English lessons if the indirect object of an active sentence is to become the subject of the passive sentence.
