The hypothetical past allows us to talk about situations that are contrary to reality — things we wish were different in the present, or things we regret from the past. It uses past tenses with a non-past meaning, a feature of the English subjunctive mood described in the Cambridge Grammar reference. For example, I wish I had studied harder for the exam expresses regret about the past, while If only I spoke French expresses a wish about the present. These structures are essential at B2 level and above.
Wish + Past Simple — Wishing the Present Were Different
Use wish + past simple to express a desire that the current situation were different (but it is not): I wish I knew the answer. (= I don't know it.) I wish she were here. (= She isn't here.) In formal English, use were for all persons: I wish it were possible. I wish he were taller.
Wish + Past Perfect — Regretting the Past
Use wish + past perfect to express regret about a past event that cannot be changed: I wish I had studied harder. (= I didn't study hard enough.) I wish they hadn't left so early. (= But they did leave early.)
Wish + Would — Annoyance or Desired Change
Use wish + would to express annoyance about someone else's behaviour or a desire for change: I wish you would stop interrupting. I wish it would stop raining. This structure cannot be used when the speaker wishes about their own behaviour — use wish + past simple instead.
If Only
If only follows the same patterns as wish but is more emphatic and emotional. It often stands alone or with an exclamation mark: If only I had known! If only she would listen!
Would Rather + Past Tense
Would rather + past tense expresses a preference about someone else's actions: I would rather you didn't tell her. I'd rather they arrived early. The past tense here is subjunctive — it refers to present or future preference, not past time.
As If / As Though
These conjunctions make comparisons with unreal situations. With past simple (present unreality): He speaks as if he knew everything. With past perfect (past unreality): She looked as though she had seen a ghost.
Common Mistakes
- Wrong: I wish I would know the answer. Correct: I wish I knew the answer. (wish + past simple for present; not wish + would for oneself)
- Wrong: I wish I studied harder last year. Correct: I wish I had studied harder last year. (past event requires past perfect)
- Wrong: I'd rather you don't mention it. Correct: I'd rather you didn't mention it. (subjunctive past tense required)

Frequently Asked Questions
What is the difference between 'wish + past simple' and 'wish + past perfect'?
'Wish + past simple' expresses a desire that the present situation were different: I wish I spoke French (but I don't). 'Wish + past perfect' expresses regret about a past event that cannot be changed: I wish I had spoken to her (but I didn't). The time reference is different: past simple = present wish; past perfect = past regret.
Why do we use 'were' (not 'was') after 'wish'?
After 'wish' expressing hypothetical situations, 'were' is the traditional formal form for all subjects: I wish I were taller. I wish she were here. This is the subjunctive mood, which signals unreality. In informal speech, 'was' is common, but 'were' is expected in IELTS and Cambridge formal writing. 'If I were you' is a fixed phrase that always uses 'were'.
When can I use 'wish + would'?
'Wish + would' expresses annoyance, complaint or a desire for change in someone else's behaviour: I wish you would stop interrupting. I wish it would stop raining. It cannot be used when the speaker is wishing about their own actions — use 'wish + past simple' instead: I wish I knew more (NOT I wish I would know more).
What is the difference between 'wish' and 'if only'?
Both express the same grammatical structures (+ past simple for present wishes; + past perfect for past regrets). 'If only' is more emphatic and emotional: If only I had known! If only she would listen! It often stands alone or is followed by an exclamation mark. 'Wish' is more neutral. 'If only' is more common in formal and literary contexts.
How is 'would rather + past tense' different from 'would rather + bare infinitive'?
'Would rather + bare infinitive' expresses the speaker's own preference: I'd rather stay home. 'Would rather + past tense' expresses a preference about someone else's actions: I'd rather you stayed home. The past tense here is subjunctive, referring to present or future preference. This is a B2+ structure.
How is 'as if' / 'as though' used with hypothetical past?
These conjunctions compare something to an unreal situation. With past simple (present unreality): He talks as if he owned the place. With past perfect (past unreality): She looked as if she had cried. In formal English, use were/had as the subjunctive form. 'As though' is slightly more formal than 'as if' but largely interchangeable.
Can 'wish' be used to express a real hope or desire?
In formal or literary English, 'wish' can introduce a positive hope: I wish you every success. I wish you well. These are set expressions. In everyday grammar, 'wish' most often expresses something unreal. To express a realistic hope, use 'hope + present/future': I hope she passes. Do not say: I wish she passes.
What is the difference between 'I regret doing' and 'I wish I had done'?
'I regret + gerund' is a formal statement of regret about a past action: I regret telling her the truth. 'I wish + past perfect' expresses the same idea more personally: I wish I hadn't told her. 'I regret + to-infinitive' introduces present bad news: I regret to inform you that... These three are easily confused because all involve regret.
How does the hypothetical past relate to the third conditional?
The third conditional (If I had studied, I would have passed) and 'wish + past perfect' both use the past perfect for imaginary past situations. The difference is structure: the third conditional is a full if-clause with a result; 'wish' expresses the desired change directly without a result clause. They often express the same situation differently.
Is the hypothetical past tested in Cambridge and IELTS exams?
Yes. Wish + past perfect, wish + would, and 'if only' are B2-C1 structures tested in FCE, CAE and IELTS Writing. Use of the subjunctive 'were' after 'wish' is a marker of C1 accuracy. In IELTS essays, expressing hypothetical alternatives (If governments had acted sooner... / If only policy had changed...) demonstrates complex grammar and strengthens argument.
