Conditionals 0, 1, and 2

You already met Zero (general truths) and First (real future) at A2. This lesson assumes you know both — the if + present, present and if + present, will + V patterns, the no-will-after-if rule, and unless / as long as. If any of that feels shaky, jump back to A2 lesson 12 before continuing.

The real B1 work is the Second conditional: the unreal, hypothetical one. It shifts the entire mental frame of the sentence from “this might happen” to “this isn’t happening, but imagine if it were.” Russian speakers find Second harder than First not because the form is complicated — it isn’t — but because Russian если бы maps onto Second in ways that produce wrong tenses if you translate word-by-word.

The three patterns side by side (recap)

Zero and First should now be muscle memory. Everything below is about row three.

Second conditional — form

Pattern: if + past simple, would / could / might + base verb.

• If I had more time, I would learn Spanish.
• If she lived in Boston, we could see her more often.
• If you ran a marathon, what would you wear?

The past tense in the if-clause is not about past time. It’s a grammatical marker of unreality — the sentence is talking about now or the imagined future, and the past form just signals “this isn’t real.”

A clean diagnostic: take If I had more time, I would learn Spanish. When is the speaker imagining this? Now. The past form had doesn’t push the situation into yesterday — it pushes it into the imagination.

The main clause uses would as the default. Could and might are also fine; they shift the modal meaning:

You can also stack a continuous: If I had more time, I would be learning Spanish — same hypothetical frame, ongoing aspect.

The framing choice — real vs hypothetical

This is the part B1 learners most often get wrong. The choice between First and Second is not about whether something is factually possible. It’s about how the speaker frames it. The same situation can take either, depending on attitude.

• If I get a job in Chicago, I’ll move there. → First. The speaker is actively applying. It feels real.
• If I got a job in Chicago, I’d move there. → Second. The speaker is idly imagining. No live application.

Both sentences are grammatical. They describe the same world. The difference is psychological — is the speaker inside the scenario as a real plan, or outside it as a thought experiment?

A few more pairs:

Notice the pattern: First sits in a world the speaker treats as live; Second sits in a world the speaker treats as imaginary, counterfactual, or remote.

Subjunctive were — the AmE rule

The Second conditional has one form that breaks the regular past simple: the verb be takes were for all subjects in standard usage, not was.

• If I were you, I’d take the offer.
• If he were here, he’d know what to do.
• If the meeting were tomorrow, we’d be ready.

This is a leftover subjunctive from older English. It survives almost exclusively in this hypothetical if / I wish environment. American English retains it actively in writing and careful speech.

Prescriptive were vs colloquial was

In everyday spoken AmE, you’ll constantly hear:

• If I was you, I’d quit.
• If she was here, she’d help.

Native speakers say this. Some of them write it. But every major US style guide (Chicago, AP, MLA) calls for were in hypothetical if I / if he / if she sentences. In academic essays, business email, news writing, and any context where editing happens, were wins. In texts to a friend, was is fine.

So the practical split:

For B1 students writing in English: default to were. It’s never wrong, and it’s the form graders, editors, and tests will expect.

Why not was?

Other past simples in Second (had, knew, lived, did) look like normal past tense. Were is the one verb form that visibly preserves the old subjunctive paradigm. Modern English flattened almost everything else.

Inversion — Were I you… (formal)

Formal English allows you to drop if and invert the subject and were. The meaning is identical to the regular Second conditional; the register is more literary.

This inversion only works with were, not with regular past simple verbs. You can’t say Had I time, I would help in Second-conditional meaning — that pattern is reserved for the Third conditional (Past Perfect → had + past participle), which is a different lesson.

Inversion shows up in:

• Legal and business writing: Were any disputes to arise, the parties shall mediate.
• Speeches and formal essays.
• Older or literary prose.

In casual conversation, nobody inverts. If I were you is what you actually say.

Russian-speaker traps specific to the Second conditional

The Second is where Russian если бы + past collides with English most painfully. Russian builds hypotheticals with бы + past tense in both clauses: Если бы у меня было время, я бы выучил испанский. The English equivalent uses past in the if-clause but would + base verb in the main clause. Two different patterns — and translation slides them together.

Trap 1: would in the if-clause

This is the most common error.

• WRONG: If I would have more time, I would learn Spanish.
• RIGHT: If I had more time, I would learn Spanish.
• WHY: Russian бы appears in both clauses (если бы… я бы…), so the brain inserts would in both. English doesn’t allow it. The if-clause uses past simple alone.

A useful internal rule: only ONE would per Second conditional, and it lives in the main clause. If you’re tempted to add a second would (or could / might) in the if-clause, stop.

Trap 2: translating если бы with present tense

• WRONG: If I have a million dollars, I would buy a house.
• RIGHT: If I had a million dollars, I would buy a house.
• WHY: Если бы у меня было contains a Russian past-tense form (было), but Russian speakers sometimes shortcut to English present because the meaning is “now.” The English Second conditional demands past simple in the if-clause precisely to mark unreality.

The English rule: if the main clause has would + V, the if-clause must have past simple (or were). No present.

Trap 3: was in writing

• Spoken AmE: If I was you… (common, not stigmatized in speech)
• Written AmE: If I were you… (the only safe choice in essays/email)
• Russian source: no equivalent, so the choice feels arbitrary

If you’re writing anything graded, edited, or professional, train yourself to type were every time. Was in writing flags you as careless to American readers, even if half the room says it out loud.

Trap 4: First when the speaker means Second

Russian doesn’t draw the real/hypothetical line as sharply, so Russians sometimes pick First where AmE expects Second:

• If I will travel to Mars, I’ll buy a spacesuit. — wrong tense AND wrong frame. Should be: If I traveled to Mars, I’d buy a spacesuit. (Second — clearly hypothetical, and no will after if anyway.)

The cue: if the situation is wildly unlikely, impossible, or purely imaginary, English defaults to Second, not First. Save First for things you actually expect might happen.

Questions and fixed phrases with Second

The Second conditional shows up heavily in fixed conversational frames. Memorize these — they buy you a lot of natural-sounding output.

Polite-advice frame

• If I were you, I would + V. — softer than direct advice.
  • If I were you, I’d talk to HR.
  • If I were you, I wouldn’t reply yet.

The full template If I were you, I would… is the single most common Second-conditional sentence in spoken AmE. Use it whenever you’d otherwise say “you should” but want to soften.

Hypothetical questions

• What would you do if…?

  • What would you do if you won the lottery?
  • What would you do if your boss asked you to lie?

• If you had to + V, would you…?

  • If you had to pick a country to live in, which would you pick?
  • If you had to choose between coffee and tea forever, which would it be?

• Would you + V + if…?

  • Would you take the job if they offered more money?

These are everyday small-talk and interview frames. They’re not exotic grammar — they’re the default vehicle for any “imagine this” conversation.

Wish-adjacent phrases

Lesson 10 covers I wish, but the pattern is the same Second-conditional logic:

• I wish I were taller. (= If I were taller, I’d be happier — same subjunctive were)
• I wish I had more time. (past form for unreal present, just like Second)

When you meet wish, recognize it as the Second-conditional family.

AmE notes

• Subjunctive were is alive and well in AmE writing. BrE has drifted toward was more readily; AmE editors actively preserve were.
• If I were you, I would is the standard polite-advice frame — vastly more common than you should in conversation.
• Would’ve + V3 is the past version (Third conditional, next lesson). At B1, don’t confuse: Second uses would + V (bare verb), not would’ve + V3.
• If + should + V for emphasis (formal): If you should see her, tell her I called. Common in business email. Roughly equivalent to if you happen to see her.
• Inversion (Were I you) is recognizable but rarely produced in everyday speech. Be able to parse it; don’t worry about producing it.

Pronunciation notes

• would /wʊd/ — short /ʊ/ vowel. I’d /aɪd/ contracts heavily; in fast speech I would collapses to /aɪd/.
• were in if I were — /wɝ/, rhotic AmE r-colored vowel. Not the BrE non-rhotic /wɜː/.
• had in the if-clause reduces: if I had → /ɪfaɪəd/ or even /ɪfaɪd/.
• If /ɪf/ — quick, unstressed; often glides: if I → /ɪˈfaɪ/.
• would’ve /ˈwʊdəv/ — note this is for Third conditional, not Second. In Second, would + bare verb, no have.

Common Russian-speaker mistakes

1. Would in both clauses: If I would have time, I would help → If I had time, I would help. Russian бы appears twice; English would only once.
2. Present in the if-clause: If I have time, I would help → If I had time, I would help. The if-clause must shift to past simple to mark unreality.
3. Was for were in writing: If I was you → If I were you (in any written or formal context).
4. First when Second is expected: If aliens will come to Earth, I’ll panic → If aliens came to Earth, I would panic. Wildly unlikely scenarios take Second.
5. Mixing First and Second: If I lived in NYC, I will be happy → pick one frame: If I lived in NYC, I would be happy (Second) or If I live in NYC, I will be happy (First).
6. Forgetting subjunctive in fixed phrases: If I was rich (in writing) → If I were rich. The If I were… template is fixed.
7. Trying inversion with the wrong verb: Had I more time, I would help (intended Second) → use If I had instead. Inversion in Second only works with were.

Summary

• Zero and First — recap from A2; don’t dwell.
• Second: if + past simple, would/could/might + base verb.
• Past in the if-clause means unreal, not past time.
• Were for all subjects in formal AmE; was is heard in casual speech but flagged in writing.
• The choice between First and Second is about framing (real plan vs hypothetical), not raw probability.
• If I were you, I would… is the everyday polite-advice frame.
• Inversion (Were I you, I would…) is formal-only; recognize it, don’t force it.
• Russian если бы maps to Second but produces wrong tenses if translated literally — one would, not two.

Next lesson: the Third conditional — if I had known, I would have called — for unreal past situations and regrets that build directly on Past Perfect and past modals.
