Second Conditional in English

Overview

The Second Conditional is used to talk about unreal, hypothetical, or unlikely situations in the present or future. It follows the pattern If + past simple, would + base verb: "If I had more money, I would travel the world." The situation is imaginary -- you are describing what you would do in a different reality.

At the CEFR B1 level, the Second Conditional is essential for expressing wishes, giving advice, and discussing imaginary scenarios. It is one of the most frequently used grammar structures in English conversation. Questions like "What would you do if...?" are extremely common in social interactions.

This conditional builds directly on the First Conditional. While the First Conditional deals with real possibilities ("If it rains, I'll stay home"), the Second Conditional deals with situations that are unlikely, impossible, or purely imaginary ("If I were a bird, I would fly away"). The key signal is the use of the past simple in the if-clause, even though the meaning is present or future.

How It Works

Basic Structure

If-clause (condition)	Main clause (result)
If + past simple	would + base verb
If I had more money,	I would travel.
If she knew the answer,	she would tell us.

The Special Case of "Were"

In formal English, were is used for all subjects with be (not was):

Informal	Formal
If I was rich...	If I were rich...
If he was here...	If he were here...

The phrase "If I were you" is always were, even in informal speech. It is a fixed expression used for giving advice.

Contractions

Full form	Contraction
I would travel	I'd travel
She would not go	She wouldn't go

When to Use It

1. Imaginary present situations: "If I spoke Chinese, I would move to Beijing."
2. Unlikely future events: "If I won the lottery, I'd buy a house."
3. Giving advice: "If I were you, I'd accept the offer."
4. Polite requests: "Would you mind if I opened the window?"

Examples in Context

English	Note
If I had money, I would travel.	Imaginary: I don't have the money
If I were you, I'd accept the job.	Advice using the fixed phrase
What would you do if you won the lottery?	Classic hypothetical question
I wouldn't buy it if it were expensive.	Negative result with were
If she lived closer, we'd see her more often.	Unlikely/hypothetical situation
If I didn't have to work, I'd sleep all day.	Imaginary freedom
He would be happier if he changed jobs.	Hypothetical outcome
If we had a car, we could drive there.	Could instead of would
Would you move abroad if you got the chance?	Question form
If I knew the answer, I'd tell you.	Implies: I don't know

Common Mistakes

Using "would" in the if-clause

• Wrong: If I would have more time, I would study.
• Right: If I had more time, I would study.
• Why: Like all English conditionals, the if-clause does not take would. Use the past simple in the if-clause and would only in the result clause.

Mixing First and Second Conditional

• Wrong: If I won the lottery, I will buy a house.
• Right: If I won the lottery, I would buy a house.
• Why: The past simple in the if-clause signals an unreal situation, which requires would (not will) in the result. Mixing them creates a grammatical mismatch.

Using "was" instead of "were" in "If I were you"

• Wrong: If I was you, I'd leave.
• Right: If I were you, I'd leave.
• Why: "If I were you" is a fixed expression that always uses were. While "was" is sometimes heard in casual speech in other contexts, "If I were you" should always use were.

Confusing the time reference

• Wrong: If I had more time yesterday, I would study. (mixing past and present)
• Right: If I had more time (now/in general), I would study.
• Why: The Second Conditional refers to the present or future, not the past. For past hypothetical situations, use the Third Conditional.

Usage Notes

The Second Conditional is the go-to structure for "what if" conversations. In social settings, questions like "What would you do if you could live anywhere?" or "If you could meet anyone in history, who would it be?" are common conversation starters.

You can use could and might instead of would in the result clause: "If I had more time, I could learn another language" (ability) / "If we left now, we might arrive on time" (possibility).

In very formal or literary English, the if-clause can be inverted without if: "Were I to know the answer, I would tell you" = "If I knew the answer, I would tell you." This is rare in everyday speech.

Both British and American English use the Second Conditional the same way. However, in informal American English, "If I was..." is more widely accepted than in British English, where "If I were..." is more consistently used.

Practice Tips

• Imagination game: Ask yourself "What would I do if...?" questions and answer them in full sentences. What would you do if you could fly? If you were invisible? If you had a time machine? This is fun and excellent practice.
• Advice practice: When friends tell you about problems, practice responding with "If I were you, I'd..." This is one of the most practical uses of the Second Conditional.
• Compare conditionals: Write the same topic as both First and Second Conditional and notice the difference: "If it rains, I'll stay home" (real possibility) vs. "If it rained every day, I would move to a desert" (hypothetical).
