What you'll learn
By the end of this lesson, you'll be able to talk about imaginary or unlikely situations using if + past simple, would + base verb, and give advice with "If I were you...".
When do I use it?
Use the second conditional for situations that are unreal, imaginary, or unlikely to happen in the present or future: "If I had a car, I would drive to work" (I do not have a car). You also use it for advice and daydreams: "If I won the lottery, I would travel the world." The condition is hypothetical, not a real plan.
How do I form it?
If + past simple, would + base verb
- If I had more time, I would start a hobby. (I do not have time now)
- If we lived by the beach, we would swim every day. (we live inland)
| If I / He / She had time | would travel |
|---|---|
| If you / we / they had time | would travel |
After the if-clause the verb is a normal past form (had, knew, won). 'Would' never appears there and never changes.
If + past simple, would + base verb
If I were you, I would apologize.
If she knew the answer, she would tell us.
Common mistakes for Spanish speakers
- "If I would..." in the if-clause. This is the classic Spanish-speaker error, carried over from the conditional "tendría, haría": "If I would be rich, I would buy a house." English allows only one "would", and it belongs in the result. The if-clause uses past simple: "If I were rich, I would buy a house."
- Using "will" in the if-clause. This mixes in the first conditional. "If I will have time" is wrong; use past simple: "If I had time, I would help you."
- Forgetting "were". For unreal situations, standard English uses "were" for I, he, she, and it: "If I were you..." (not "If I was you"). Spanish "si yo fuera" follows the same subjunctive idea.
Count the "would"s: a correct second conditional has exactly one, always in the result half. If the Spanish "si" clause uses "ía/ía would" (tendría, haría), in English that whole clause becomes a normal past verb: had, were, knew, won.
