Second conditional (+ wish / if only)

B1 35 / 50

In short

Use the second conditional to talk about present or future situations that are unreal, imaginary, or unlikely: if + past simple, would + base verb. The past tense here means “not real,” not “past time.”

The rule

The second conditional imagines a situation that is not true now (or is very unlikely to happen) and gives its result.

PartFormExample
If-clause (the imaginary situation)if + past simpleIf I had a car, …
Main clause (the imagined result)would / could / might + base verb… I would drive to work.
  • would (‘d) = the normal/probable result: If I won, I would celebrate.
  • could = would be able to / would be possible: If I had more money, I could travel.
  • might = the result is possible but not certain: If you asked her, she might say yes.

The past simple does not mean the past. It is a “distance” signal that tells the listener the situation is imaginary.

were for all persons. In careful English we use were (not was) for I/he/she/it after if: If he were taller, he could be a model. / If it weren’t so late, we’d stay. (was is common in speech, but were is the safe, correct choice.)

If I were you, I'd ... is the fixed formula for giving advice: If I were you, I’d apologise.

Second vs first conditional (see lesson 28). The first conditional is for real, possible future situations; the second is for unreal or unlikely ones.

Formif + present, will + baseif + past, would + base
ExampleIf it rains, I’ll stay home.If it snowed in July, I’d be shocked.

Comma: when the if-clause comes first, put a comma after it. When it comes second, no comma: If I knew, I’d tell you. / I’d tell you if I knew.

Forms & patterns

Second conditional:

If-clauseMain clause
If + subject + past simplesubject + would / could / might + base verb
If I lived abroad,I would learn the language.
If she were here,she could help us.

wish / if only. These express a wish that the present were different (a present regret) - same “unreal past” idea.

UseFormExample
Present regret / unreal wishwish / if only + past simpleI wish I had more time.
With bewish / if only + wereI wish I were taller.
Annoyance / wanting changewish / if only + would + baseI wish you would listen.

If only is just a stronger, more emotional version of wish: If only I knew his name!

wish + would is used for something that annoys you or that you want to change - usually another person’s behaviour or a situation outside your control. You normally don’t use wish + would about yourself.

Examples

EnglishNote
If I won the lottery, I’d travel the world.Imaginary future; won = unreal, not past.
If I had more time, I would help you with this.Present situation that is not true.
If he were taller, he’d play basketball.were with he in careful English.
If I were you, I’d take the job.Fixed advice formula.
If it snowed in July, everyone would be amazed.Very unlikely - second, not first, conditional.
I wish I had a bigger flat.Present regret about a real situation.
If only I knew his name!Strong unreal wish about now.
I wish you would stop interrupting me.wish + would = annoyance at someone’s behaviour.
I wish it would stop raining.Wanting a situation to change.

Common mistakes

  • If I will have time, I would help. -> If I had time, I would help. - after if use the past simple, never will/would.
  • If I would win, I’d be happy. -> If I won, I’d be happy. - would goes only in the main clause.
  • I wish I have more money. -> I wish I had more money. - wish about now takes the past simple.
  • I wish you would be taller. -> I wish you were taller. - use wish + past/were for states; wish + would is for changeable actions/annoyance.
  • If I knew it I would tell you. -> If I knew it, I would tell you. - comma after a leading if-clause.

Tips

  • “Past form = unreal, not past time.” This one idea unlocks both the second conditional and wish.
  • For advice, just reach for the ready-made phrase If I were you, I’d …
  • Quick test: real and likely? -> first conditional (if + present, will). Imaginary or unlikely? -> second (if + past, would).
  • Remember the split: wish + past = a state you regret; wish + would = an action you want to change or that annoys you.
