Conditional Sentence

Conditional Sentences are also known as Conditional Clauses or If Clauses. They are used to express that the action in the main clause (without if) can only take place if a certain condition (in the clause with if) is fulfilled. There are three types of Conditional Sentences.

Conditional Sentence Type 1

→ It is possible and also very likely that the condition will be fulfilled.

Form: if + Simple Present, will-Future

Example: If I find her address, I’ll send her an invitation.

Conditional Sentence Type 2

→ It is possible but very unlikely, that the condition will be fulfilled.

Form: if + Simple Past, Conditional I (= would + Infinitive)

Example: If I found her address, I would send her an invitation.

more on Conditional Sentences Type II ►

Conditional Sentence Type 3

→ It is impossible that the condition will be fulfilled because it refers to the past.

Form: if + Past Perfect, Conditional II (= would + have + Past Participle)

Example: If I had found her address, I would have sent her an invitation.

1.IF Clause Type 1

Form

if + Simple Present, will-Future.

(a)Example

If I find her address, I will send her an invitation.

Note : The main clause can also be at the beginning of the sentence. In this case, don’t use a comma.

(b)Example:

I will send her an invitation if I find her address.

Note: Main clause and / or if clause might be negative. See Simple Present und will-Future on how to form negative sentences.

Use

Conditional Sentences Type I refer to the future. An action in the future will only happen if a certain condition is fulfilled by that time. We don’t know for sure whether the condition actually will be fulfilled or not, but the conditions seems rather realistic – so we think it is likely to happen.

(a)Example:

If I find her address, I’ll send her an invitation.

I want to send an invitation to a friend. I just have to find her address. I am quite sure, however, that I will find it.

(b)Example

If John has the Money, he will buy a Ferrari.

I know John very well and I know that he earns a lot of money and that he loves Ferraris. So I think it is very likely that sooner or later he will have the money to buy a Ferrari.

2.IF Clause Type 2

→ It is possible but very unlikely, that the condition will be fulfilled.

Form

if + Simple Past, main clause with Conditional I (= would + Infinitive)

(a)Example

à If I found her address, I would send her an invitation.

Note :

1.The main clause can also be at the beginning of the sentence. In this case, don’t use a comma.

2.Main clause and / or if clause might be negative. See Simple Past und Conditional I on how to form negative sentences.

3.Were instead of Was

In IF Clauses Type II, we usually use ‚were‘– even if the Pronoun is I, he, she or it –.

Example

If I were you, I would not do this.

Use

Conditional Sentences Type II refer to situations in the present. An action could happen if the present situation were different. I don’t really expect the situation to change, however. I just imagine „what would happen if …“

(a)Example

If I found her address, I would send her an invitation.

I would like to send an invitation to a friend. I have looked everywhere for her address, but I cannot find it. So now I think it is rather unlikely that I will eventually find her address.

(b)Example

If John had the money, he would buy a Ferrari.

( I know John very well and I know that he doesn’t have much money, but he loves Ferraris. He would like to own a Ferrari (in his dreams). But I think it is very unlikely that he will have the money to buy one in the near future.)

3.IF Clause Type 3

It is impossible that the condition will be fulfilled because it refers to the past.

Form

if + Past Perfect, main clause with Conditional II

(a)Example

If I had found her address, I would have sent her an invitation.

Note : The main clause can also be at the beginning of the sentence. In this case, don’t use a comma.

(b)Example: I would have sent her an invitation if I had found her address.

Note: Main clause and / or if clause might be negative. See Past Perfect and Conditional II on how to form negative sentences.

(c)Example

If I hadn’t studied, I wouldn’t have passed my exams.

Use

Conditional Sentences Type III refer to situations in the past. An action could have happened in the past if a certain condition had been fulfilled. Things were different then, however. We just imagine, what would have happened if the situation had been fulfilled.

(a)Example

If I had found her address, I would have sent her an invitation.

Here Sometime in the past, I wanted to send an invitation to a friend. I didn’t find her address, however. So in the end I didn’t send her an invitation.

(b)Example

If John had had the money, he would have bought a Ferrari.

Here I knew John very well and I know that he never had much money, but he loved Ferraris. He would have loved to own a Ferrari, but he never had the money to buy one.

English conditionals are used to talk about hypothetical situations. There are four main types of conditionals: zero, first, second, and third.

Zero Conditional

The zero conditional is used to talk about general truths or facts. It is formed with the simple present Tense in both the if clause and the main clause.

For example:

If you heat water, it boils.
If you add sugar to coffee, it tastes sweet.
If you drop a ball, it will fall.

First Conditional

The first conditional is used to talk about possible or probable events in the future. It is formed with the simple present tense in the if clause and the future simple tense in the main clause.

For example:

If I study hard, I will pass the exam.
If you water the Plants, they will grow.
If you go to bed early, you will be tired.

Second Conditional

The second conditional is used to talk about unlikely or impossible events in the present or future. It is formed with the past simple tense in the if clause and the would + infinitive in the main clause.

For example:

If I had studied harder, I would have passed the exam.
If you watered the plants, they would grow.
If you went to bed early, you would be tired.

Third Conditional

The third conditional is used to talk about regrets or hypothetical situations in the past. It is formed with the past perfect in the if clause and the would have + past participle in the main clause.

For example:

If I had studied harder, I would have passed the exam.
If you had watered the plants, they would have grown.
If you had gone to bed early, you would have been tired.

Mixed Conditionals

Mixed conditionals are used to talk about a combination of real and hypothetical situations. They can be formed in a variety of ways, but the most common is to use the past simple or past perfect in the if clause and the would + infinitive or would have + past participle in the main clause.

For example:

If I had studied harder, I would have passed the exam, but I didn’t, so I failed.
If you had watered the plants, they would have grown, but you didn’t, so they died.
If you had gone to bed early, you would have been tired, but you didn’t, so you’re not.

Conditionals can be a bit tricky, but with a little practice, you’ll be using them like a native speaker in no time!

What is a conditional sentence?
A conditional sentence is a sentence that expresses a condition or supposition. It is made up of two clauses: the “if” clause and the “main” clause. The “if” clause expresses the condition, and the “main” clause expresses the result of the condition.
What are the different types of conditional sentences?
There are four main types of conditional sentences:
Zero conditional: This type of conditional sentence is used to talk about general truths or facts. The “if” clause can be in the present tense or the past tense, and the “main” clause is always in the simple present tense.
First conditional: This type of conditional sentence is used to talk about possible or probable events. The “if” clause is in the present tense, and the “main” clause is in the future tense.
Second conditional: This type of conditional sentence is used to talk about unlikely or impossible events. The “if” clause is in the past tense, and the “main” clause is in the past perfect tense.
Third conditional: This type of conditional sentence is used to talk about regrets or hypothetical situations. The “if” clause is in the past perfect tense, and the “main” clause is in the past perfect subjunctive.
How do you use conditional sentences?
Conditional sentences are used to express a variety of meanings, including:
Possibility: “If you study hard, you will pass the test.”
Probability: “If it rains, I will take an umbrella.”
Impossibility: “If I were rich, I would buy a house.”
Necessity: “If you want to get a good job, you need to go to college.”
Advice: “If you are going to the beach, you should wear sunscreen.”
Warning: “If you touch that fire, you will get burned.”
Offer: “If you are hungry, I can make you some food.”
Request: “If you could help me with this, I would appreciate it.”
Permission: “If you want to go out, you need to be home by 11:00.”
Permission to refuse: “If you don’t want to go out, that’s okay.”
Concession: “Even if you don’t want to go out, I’m still going.”
Contrast: “I would go out with you, but I have to work.”
Cause and effect: “If you don’t study, you will fail the test.”
Condition: “I will go to the store if you give me a ride.”
Supposition: “If I were you, I would do it differently.”
Regret: “If I had known, I would have done it differently.”
Wish: “If only I had known, I would have done it differently.”
What are some common mistakes people make with conditional sentences?
Some common mistakes people make with conditional sentences include:
Using the wrong tense in the “if” clause.
Using the wrong tense in the “main” clause.
Using the wrong type of conditional sentence.
Not using the correct punctuation.
Not using the correct word order.
How can you avoid making mistakes with conditional sentences?
The best way to avoid making mistakes with conditional sentences is to practice using them. You can do this by reading and writing conditional sentences, and by asking a native speaker to correct your mistakes. You can also find many Resources online that can help you learn about conditional sentences.
