What would you do if you received a job offer abroad? How would your life be different if you had chosen another subject at university? Hypothetical situations in English let you explore imagined choices, give advice, consider alternatives, and talk about regrets.
The key is to decide when the situation belongs and how you want to present it. A real possibility tomorrow, an imaginary situation now, and a different version of yesterday need different verb patterns. This guide compares those patterns and gives you conversations and exercises to practise them.

What Is a Hypothetical Situation?
A hypothetical situation is something you ask someone to imagine. It may be impossible, contrary to a known fact, or simply an option you are considering: If we opened a second office, where would it be? The speaker is exploring an idea without saying that it will happen.
A conditional sentence connects a condition with a result. In If I worked from home, I would save money on transport, working from home is the imagined condition; saving money is the imagined result. You can reverse the order: I would save money on transport if I worked from home.
Normally, put a comma after an opening if-clause, but do not add one when the if-clause comes second. For more on how these two parts work, see Cambridge’s explanation of conditional sentences.
Real Possibility or Imagined Alternative?
Compare these sentences about the same decision: If I get the promotion, I will move to Bristol and If I got the promotion, I would move to Bristol. The first presents the promotion as an open future possibility. The second makes the discussion more tentative or imaginary; it does not necessarily mean the promotion is impossible.
The following patterns are useful starting points. The zero conditional is included for comparison because general facts and habits are different from imagining an alternative reality.
| Pattern | Main use | Example |
|---|---|---|
| Zero: if + present, present | A general fact or repeated result | If I skip lunch, I get hungry in the afternoon. |
| First: if + present, will + base verb | An open future possibility | If the meeting finishes early, I will call you. |
| Second: if + past, would + base verb | An imagined present or future situation | If I had a quieter office, I would concentrate better. |
| Third: if + past perfect, would have + past participle | An alternative past | If I had saved the file, I would not have lost my work. |
These names describe common patterns, not every possible conditional sentence. Speakers also use modals such as could and might when they want a different meaning.
The Second Conditional: Imagining Now or Later
Use if + past simple with would + base verb for an imagined present or future situation: If I knew the answer, I would tell you. Here, knew does not describe yesterday. It signals distance from the present reality: I do not know the answer.
Time expressions make the meaning clearer: If I had tomorrow off, I would visit my sister. Although had looks like a past tense, tomorrow places the imagined situation in the future. You can also make the result negative: If I lived closer, I would not need a car.
Should You Say “If I Was” or “If I Were”?
For an unreal situation, were can be used with every subject: If she were the manager, she would change the schedule. It is a useful choice in formal writing and in the advice expression If I were you. You will also hear was with singular subjects in informal hypothetical sentences, as the British Council’s conditional guide explains.
For advice, try If I were you, I would ask for more information before accepting. When you ask a hypothetical question, put would before the subject in the question clause: What would you ask if you were in my position?
The Third Conditional: Imagining a Different Past
The third conditional changes a completed past event in your imagination. Its common pattern is if + had + past participle, followed by would have + past participle.
Suppose Maya missed the application deadline and could not attend an interview. She can say, If I had applied on time, I would have had a chance to interview. This imagines a different application date and a different past opportunity; it does not claim that she would definitely have got the job.
Negative forms let you explore things that went well, too: If you had not reminded me, I would have missed the deadline. The reminder happened, so the missed deadline is the imagined alternative. This structure can express appreciation as well as regret.
Understanding “I’d” and “Would’ve”
In If I’d checked the address, I would’ve arrived on time, the first contraction means I had; the second means I would have. Compare I’d check the address if I were you, where I’d means I would.
The following verb helps you interpret the contraction: I’d checked contains a past participle, while I’d check contains a base verb. In writing, use would have or would’ve, not would of.
Mixed Conditionals: Connecting Different Times
A mixed conditional links a condition and result that belong to different times. Identify each time separately before choosing the verbs. The British Council’s guide to third and mixed conditionals covers both combinations below.
A Past Choice with a Present Result
If I had accepted the transfer last year, I would live in Madrid now. The imagined choice belongs to last year, while the imagined home belongs to the present. Use if + past perfect with would + base verb.
Compare If I had accepted the transfer, I would have moved to Madrid last year. Both parts now refer to the past, so this version is a third conditional.
A Present Characteristic with a Past Result
If I were more confident, I would have asked a question at yesterday’s meeting. The speaker sees a lack of confidence as a continuing characteristic that also affected yesterday. Use if + past simple with would have + past participle.
If you mean only a temporary feeling during that meeting, use a past condition instead: If I had felt more confident yesterday, I would have asked a question. The intended meaning determines the pattern.

Choosing Between Would, Could, and Might
Changing the modal changes what you say about the imagined result. Compare the same condition with three endings:
| Sentence | Meaning in this example |
|---|---|
| If we had a bigger budget, we would hire a designer. | Hiring is the result we envisage or intend. |
| If we had a bigger budget, we could hire a designer. | Hiring would become an available option. |
| If we had a bigger budget, we might hire a designer. | Hiring is a possible result, but we are not committed to it. |
For an alternative past, use could have or might have plus a past participle: If we had advertised earlier, we might have received more applications. This leaves the result uncertain. These modals do not correspond to fixed probability percentages.
Should often gives advice rather than an imagined consequence: If you receive an offer, you should read the contract carefully. Compare that with If I received an offer, I would ask about working hours, which describes an imagined response.
Wish, If Only, and Other Useful Expressions
Wishes About the Present and the Past
Use wish + past simple for a present situation you want to change: I wish I understood this software. For a past regret, use wish + past perfect: I wish I had saved a backup copy.
If only can make the wish stronger: If only I had more free time! Use wish + would when you want something to change, often with frustration: I wish my neighbours would turn the music down. The British Council’s lesson on wishes explains these distinctions.
For an open possibility, hope is usually the natural choice: I hope I get the job. Compare I wish I had got the job, which expresses regret about an unsuccessful past outcome.
What If, Suppose, and Would Rather
What if we changed the launch date? and Suppose you could work anywhere. Where would you go? invite someone to explore an idea. They are useful when a conversation needs alternatives rather than a firm prediction.
To express a preference about your own action, use would rather + base verb: I’d rather work from home. With a different subject, use a past form for a present or future preference: I’d rather you called tomorrow. See Cambridge’s guide to would rather for further examples.
In more formal writing, you may also see Had we received your message, we would have replied sooner. This means If we had received your message… Our guide to inverted conditionals with should, were, and had explains this optional structure.
Short Conversations for Everyday Situations
Giving Advice to a Colleague
Sam: “They’ve offered me a role with more travel. What would you do if you were me?”
Leah: “I’d ask how often I’d need to be away. If I were you, I wouldn’t decide before knowing that.”
Leah imagines herself in Sam’s position. Her answer gives a specific next step instead of making the decision for him.
Reviewing a Missed Opportunity
Ana: “We didn’t hear about the workshop until Friday.”
Ben: “If we’d known earlier, we could have registered.”
Ana: “Let’s sign up for their newsletter so we hear about the next one.”
Could have registered describes an opportunity that was unavailable because they heard too late. The conversation then moves from an imagined past to a practical future action.
Discussing a Possible Change
Noor: “What if we moved the weekly meeting to Thursday?”
Eli: “That might work. If we met after lunch, the whole team could attend.”
The past forms here help the speakers explore a proposal. They are discussing a possible future arrangement, not a meeting that happened last week.
Common Mistakes and How to Correct Them
Putting would in both clauses: For a standard imagined condition, change If I would have more time, I would cook to If I had more time, I would cook. However, would after if is possible for meanings such as willingness or a polite request: If you would wait here, I will find someone to help. Cambridge discusses this use in its guide to if.
Using a past form after would: Change I would went to I would go for an imagined present or future action. For an alternative past, use I would have gone.
Choosing the pattern without checking the time: To express a past regret, change I wish I study more last year to I wish I had studied more last year. First locate the situation in time; then choose the verb form.
Practice: Choose the Form That Matches the Meaning
Complete each sentence using the verb in brackets. Follow the stated time or pattern so that your answer expresses the intended meaning. Write your answers before checking the explanations.
- I do not own a car. Use the second conditional: If I _____ (own) a car, I would drive to work.
- The result is still an open future possibility. Use the first conditional: If the parcel _____ (arrive) tomorrow, I will bring it to you.
- Give advice using the formal unreal form of be: If I _____ (be) you, I would keep a copy.
- I did not check yesterday’s forecast. Use the third conditional: If I _____ (check) it, I would have taken an umbrella.
- The reminder prevented a past mistake: If you had not reminded me, I _____ (would / forget) yesterday’s appointment.
- I turned down the transfer last year and do not live in Rome now: If I had accepted it, I _____ (would / live) in Rome now.
- My continuing fear of heights stopped me yesterday: If I were not afraid of heights, I _____ (would / join) yesterday’s climbing trip.
- I cannot understand my neighbour’s language: I wish I _____ (can) understand it.
- I regret sending that email yesterday: I wish I _____ (not / send) it.
- Express a preference about someone else’s future action: I’d rather you _____ (call) me tomorrow.
Answers and Explanations
- owned. The past form marks an imagined present condition. It does not mean that you owned a car in the past.
- arrives. In this first conditional, use present simple in the if-clause even though tomorrow refers to the future.
- were. If I were you is the standard expression used here to imagine another person’s position and give advice.
- had checked. Both the missed check and the imagined result belong to yesterday, so the condition uses past perfect.
- would have forgotten. The result is an alternative past. The past participle of forget is forgotten, not forgot.
- would live. This mixed conditional links last year’s decision to a present result. Now makes the result’s time explicit.
- would have joined. The general characteristic is connected to a missed past activity, so the result uses would have + past participle.
- could. I wish I could understand it expresses a desired ability that the speaker currently lacks.
- had not sent or hadn’t sent. A regret about a completed past action takes past perfect after wish.
- called. With different subjects, would rather takes a past form to express this preference about tomorrow.
Put the Patterns into Your Own Words
Choose one decision from work, study, or everyday life. Write an imagined present alternative, a different past choice, and a past choice with a present result. Add a reason to each sentence so that you practise explaining an idea rather than only completing a formula.
For example: If I had a shorter commute, I would take an evening course because I would have more time. If I had taken that course last year, I would have learned the basics before starting my new job. If I had continued studying, I would feel more confident now.
Read your sentences aloud and identify the time of each condition and result. If those times match your intended meaning, you have a practical way to choose between second, third, and mixed conditionals in your next conversation.
