Second Conditional — Complete Guide with Examples
The second conditional imagines unreal or unlikely situations: If I had a million dollars, I'd buy an island. Past forms, present meaning — the tense is a signal of distance from reality, not of time.
Form and meaning
If + past simple, would + base verb: "If I knew the answer, I would tell you" (= I don't know it). It covers impossible presents ("If I were taller…"), unlikely futures ("If I won the lottery…"), and advice ("If I were you, I'd apologise").
The past tense here does NOT mean past time. "If I had wings" is about now — an imaginary now.
Were, would, and could
"If I were you" — traditional grammar uses were for all persons in this structure, and it remains the safest choice in writing and exams; "if I was" is common in speech.
The result clause can soften with could or might: "If we left now, we could catch the early train." Contractions: I'd = I would.
| Pattern | Example |
|---|---|
| If + past, would | If she studied more, she would pass. |
| Advice formula | If I were you, I'd take the job. |
| With could | If he trained daily, he could go pro. |
| Question | What would you do if you saw a ghost? |
Common mistakes
✓ If I had money, I would travel.
No would inside the if-clause.
✓ If I were you, I'd take the job.
Unreal situations use past forms + would.
✓ If she went to the moon, she would float.
Keep both clauses in second-conditional form for unreal meaning.

FAQ
What is the second conditional used for?
Imaginary, unlikely, or impossible situations in the present or future: If I had more time, I would learn piano. It also gives advice: If I were you, I'd call them.
Why does it use the past tense for present meaning?
The past form signals distance from reality, not past time. "If I knew" means I don't know now.
Is "if I was you" wrong?
In careful or written English, prefer "if I were you" — the subjunctive were. "If I was" appears in casual speech but can cost marks in exams.
