Future Conditionals

Future Real Conditional

FORM

[If / When … simple present …, … simple future …]

[… simple future … if / when … simple present …]

Notice that there is no future in the if- or when-clause.

USE

The future real conditional (also called conditional 1) describes what you think you will do in a specific situation in the future. It is different from other real conditional forms because, unlike the present or the past, you do not know what will happen in the future. Although this form is called “real”, you are usually imagining or guessing about the future. It is called “real” because it is still possible that the action might occur in the future. Carefully study the following examples and compare them to the future unreal conditional examples further down the page.

Examples:

• If I go to my friend’s house for dinner tonight, I will take a bottle of wine or some flowers.
  I am still not sure if I will go to his house or not.
• When I have a day off from work, I am going to go to the beach.
  I have to wait until I have a day off.
• If the weather is nice, she is going to walk to work.
  It depends on the weather.
• Jerry will help me with my homework when he has time.
  I have to wait until he has time.
• I am going to read if there is nothing on TV.
  It depends on the TV schedule.
• A: What are you going to do if it rains?
  B: I am going to stay at home.

IMPORTANT If / When

Both “if” and “when” are used in the future real conditional, but the use is different from other real conditional forms. In the future real conditional, “if” suggests that you do not know if something will happen or not. “When” suggests that something will definitely happen at some point; we are simply waiting for it to occur. Notice also that the Simple Future is not used in if-clauses or when-clauses.

Examples:

• When you call me, I will give you the address.
  You are going to call me later, and at that time, I will give you the address.
• If you call me, I will give you the address.
  If you want the address, you can call me.

Future Unreal Conditional

FORM 1 (Most Common Form)

[If … simple past …, … would + verb …]

[… would + verb … if … simple past …]

Notice that this form looks the same as Present Unreal Conditional.

USE

The future unreal conditional is used to talk about imaginary situations in the future. It is not as common as the future real conditional because English speakers often leave open the possibility that anything MIGHT happen in the future. It is only used when a speaker needs to emphasize that something is impossible. Because this form looks like Present Unreal Conditional, many native speakers prefer Form 2 described below.

Examples:

• If I had a day off from work next week, I would go to the beach.
  I don’t have a day off from work.
• I am busy next week. If I had time, I would come to your party.
  I can’t come.
• Jerry would help me with my homework tomorrow if he didn’t have to work.
  He does have to work tomorrow.

FORM 2

[If … were + present participle …, … would be + present participle …]

[… would be + present participle … if … were + present participle …]

USE

Form 2 of the future unreal conditional is also used to talk about imaginary situations in the future. Native speakers often prefer this form over Form 1 to emphasize that the conditional form is in the future rather than the present. Also notice in the examples below that this form can be used in the if-clause, the result, or both parts of the sentence.

Examples:

• If I were going to Fiji next week, I would be taking my scuba diving gear with me. In if-clause and result
  I am not going to go to Fiji and I am not going to take my scuba gear with me.
• If I were not visiting my grandmother tomorrow, I would help you study. In if-clause
  I am going to visit my grandmother tomorrow.
• I am busy next week. If I had time, I would be coming to your party. In result
  I am not going to come to your party.

FORM 3

[If … were going to + verb …, … would be + present participle …]

[… would be + present participle … if … were going to + verb …]

USE

Form 3 of the future unreal conditional is a variation of Form 2 which is also used to talk about imaginary situations in the future. Notice that this form is only different from Form 2 in the if-clause. Native speakers use Form 3 to emphasize that the conditional form is a plan or prediction in the same way “be going to” is used to indicate a plan or prediction.

Examples:

• If I were going to go to Fiji next week, I would be taking my scuba diving gear with me.
  I am not going to go to Fiji and I am not going to take my scuba gear with me.
• If I were not going to visit my grandmother tomorrow, I would help you study.
  I am going to visit my grandmother tomorrow.

IMPORTANT Only use “If”

Only the word “if” is used with the past unreal conditional because you are discussing imaginary situations. “When” cannot be used.

Examples:

• I would buy that computer tomorrow when it were cheaper. Not Correct
• I would buy that computer tomorrow if it were cheaper. Correct

EXCEPTION Conditional with Modal Verbs

There are some special conditional forms for modal verbs in English:

would + can = could

would + shall = should

would + may = might

The words “can,” “shall” and “may” cannot be used with “would.” Instead, they must be used in these special forms.

Examples:

• If I went to Egypt next year, I would can learn Arabic. Unfortunately, that’s not possible. Not Correct
• If I went to Egypt next year, I could learn Arabic. Unfortunately, that’s not possible. Correct

The words “could,” should,” “might” and “ought to” include conditional, so you cannot combine them with “would.”

Examples:

• If I didn’t have to work tonight, I would could go to the fitness center. Not Correct
• If I didn’t have to work tonight, I could go to the fitness center. Correct

Future Real Conditional vs. Future Unreal Conditional

To help you understand the difference between the future real conditional and the future unreal conditional, compare the examples below:

Examples:

• If you help me move tomorrow, I will buy you dinner. Future Real Conditional
  I don’t know if you can help me.
• If you helped me move tomorrow, I would buy you dinner. Future Unreal Conditional
  You can’t help me, or you don’t want to help me.

• There are four types of conditional sentences.
• It’s important to use the correct structure for each of these different conditional sentences because they express varying meanings.
• Pay attention to verb tense when using different conditional modes.
• Use a comma after the if-clause when the if-clause precedes the main clause.

Conditional sentences are statements discussing known factors or hypothetical situations and their consequences. Complete conditional sentences contain a conditional clause (often referred to as the if-clause) and the consequence. Consider the following sentences:

If a certain condition is true, then a particular result happens.

I would travel around the world if I won the lottery.

When water reaches 100 degrees, it boils.

What Are the Different Types of Conditional Sentences?

There are four different types of conditional sentences in English. Each expresses a different degree of probability that a situation will occur or would have occurred under certain circumstances.

• Zero Conditional Sentences
• First Conditional Sentences
• Second Conditional Sentences
• Third Conditional Sentences

Let’s look at each of these different types of conditional sentences in more detail.

How to Use Zero Conditional Sentences

Zero conditional sentences express general truths—situations in which one thing always causes another. When you use a zero conditional, you’re talking about a general truth rather than a specific instance of something. Consider the following examples:

If you don’t brush your teeth, you get cavities.

When people smoke cigarettes, their health suffers.

There are a couple of things to take note of in the above sentences in which the zero conditional is used. First, when using the zero conditional, the correct tense to use in both clauses is the simple present tense. A common mistake is to use the simple future tense.

When people smoke cigarettes, their health will suffer
.

Secondly, notice that the words if and when can be used interchangeably in these zero conditional sentences. This is because the outcome will always be the same, so it doesn’t matter “if” or “when” it happens.

How to Use First Conditional Sentences

First conditional sentences are used to express situations in which the outcome is likely (but not guaranteed) to happen in the future. Look at the examples below:

If you rest, you will feel better.

If you set your mind to a goal, you’ll eventually achieve it.

Note that we use the simple present tense in the if-clause and simple future tense in the main clause—that is, the clause that expresses the likely outcome. This is how we indicate that under a certain condition (as expressed in the if-clause), a specific result will likely happen in the future. Examine some of the common mistakes people make using the first conditional structure:

If you will rest
, you will feel better.

If you rest
, you will feel better.

Explanation: Use the simple present tense in the if-clause.

If you set your mind to a goal, you eventually achieve
 it.

If you set your mind to a goal, you’ll eventually achieve
 it.

Explanation: Use the zero conditional (i.e., simple present + simple present) only when a certain result is guaranteed. If the result is likely, use the first conditional (i.e., simple present + simple future).

How to Use Second Conditional Sentences

Second conditional sentences are useful for expressing outcomes that are completely unrealistic or will not likely happen in the future. Consider the examples below:

If I inherited a billion dollars, I would travel to the moon.

If I owned a zoo, I might let people interact with the animals more.

Notice the correct way to structure second conditional sentences is to use the simple past tense in the if-clause and an auxiliary modal verb (e.g., could, should, would, might) in the main clause (the one that expresses the unrealistic or unlikely outcome). The following sentences illustrate a couple of the common mistakes people make when using the second conditional:

If I inherit
 a billion dollars, I would travel to the moon.

If I inherited
 a billion dollars, I would travel to the moon.

Explanation: When applying the second conditional, use the simple past tense in the if-clause.

If I owned a zoo, I will let
 people interact with the animals more.

If I owned a zoo, I might let
 people interact with the animals more.

Explanation: Use a modal auxiliary verb in the main clause when using the second conditional mood to express the unlikelihood that the result will actually happen.

How to Use Third Conditional Sentences

Third conditional sentences are used to explain that present circumstances would be different if something different had happened in the past. Look at the following examples:

If you had told me you needed a ride, I would have left earlier.

If I had cleaned the house, I could have gone to the movies.

These sentences express a condition that was likely enough, but did not actually happen in the past. The speaker in the first sentence was capable of leaving early, but did not. Along these same lines, the speaker in the second sentence was capable of cleaning the house, but did not. These are all conditions that were likely, but regrettably did not happen.

Note that when using the third conditional, we use the past perfect (i.e., had + past participle) in the if-clause. The modal auxiliary (would, could, should, etc.) + have + past participle in the main clause expresses the theoretical situation that could have happened.

Consider these common mistakes when applying the third conditional:

If you would have told
 me you needed a ride, I would have left earlier.

If you had told
 me you needed a ride, I would have left earlier.

Explanation: With third conditional sentences, do not use a modal auxiliary verb in the if-clause.

If I had cleaned the house, I could go
 to the movies.

If I had cleaned the house, I could have gone
 to the movies.

Explanation: The third conditional mood expresses a situation that could have only happened in the past if a certain condition had been met. That’s why we use the modal auxiliary verb + have + the past participle.

Exceptions and Special Cases When Using Conditional Sentences

As with most topics in the English language, conditional sentences often present special cases in which unique rules must be applied.

Use of the Simple Future in the If-Clause

Generally speaking, the simple future should be used only in the main clause. One exception is when the action in the if-clause will take place after the action in the main clause. For example, consider the following sentence:

If aspirin will ease my headache, I will take a couple tonight.

The action in the if-clause is the aspirin easing the headache, which will take place only after the speaker takes them later that night.

“Were to” in the If-Clause

The verb phrase were to is sometimes used in conditional sentences when the likely or unlikely result is particularly awful or unthinkable. In this case, were to is used to place emphasis on this potential outcome. Consider these sentences:

If I were to
 be sick, I would miss another day of work.

If she were to
 be late again, she would have to have a conference with the manager.

If the rent were to
 have been a penny more, they would not have been able to pay it.

Note that the emphatic “were to” can be used to describe hypothetical scenarios in the present, future, and past.

Punctuating Conditional Sentences

Despite the complex nature of conditional sentences, punctuating them properly is really simple!

Here’s the skinny:

Use a comma after the if-clause when the if-clause precedes the main clause.

If I’d had time, I would have cleaned the house.

If the main clause precedes the if-clause, no punctuation is necessary.

I would have cleaned the house if I’d had time.
