Conditionals Overview — Real vs. Unreal

Step 1

Quick Look

A conditional sentence has two parts: the IF-clause (the condition) and the result clause. English sorts all conditionals into two families — REAL (possible, factual) and UNREAL (imaginary, impossible). Master the family system first; the individual conditionals become easy after that.
Sentence TypeStructure + Example
Structure
If+condition, result.
If it rains, we will cancel the site visit.
Order is flexible
Result+if+condition (no comma)
We will cancel the site visit if it rains.
The comma rule
If-clause FIRST comma after it. Result clause first no comma.

The golden rule of all conditionals: UNREAL = one step back in time. To show something is imaginary, English shifts the tense backwards — present ideas use past tense, past ideas use past perfect. This single trick unlocks every unreal conditional in this module.

Two clauses, two orders
IF-CLAUSEFIRSTRESULTFIRSTIFIf it rains,RESULTwe will cancel the site visit.comma afterthe if-clauseRESULTWe will cancel the site visitIFif it rains.no comma
Same meaning either way: the comma depends only on which clause comes first.
Step 2

When to Use It

REAL fact habit futureUNREAL imagine dream regret
Use 1

The REAL family — things that do or can happen

Facts, habits, and possible futures. Normal tenses, no shifting.
  • If you heat ice, it melts. (fact — always true)
  • If the client agrees, we will sign tomorrow. (possible future)
  • If I had free time in those days, I visited the site myself. (real past habit)
REAL fact habit futureUNREAL imagine dream regret
Use 2

The UNREAL family — imagination, dreams, regrets

Tense shifts one step back to signal ‘this is not reality’.
  • If I had ₹10 crore, I would buy that corner plot. (I don’t have it — imaginary present)
  • If we had launched last year, we would have beaten the competition. (we didn’t — past regret)
fall + willfell + wouldREALI think prices may fallUNREALI doubt prices will fall
Use 3

Spot the difference — same idea, two families

Watch how the tense shift changes the meaning:
  • If prices fall, I will buy. (REAL — I think they may fall)
  • If prices fell, I would buy. (UNREAL — I doubt they will fall)
  • The facts are identical; the speaker’s belief is different.
IFRESULTwillwouldwillwouldsimple tense onlywill / would live here
Use 4

The one rule that never changes

WILL and WOULD almost never enter the if-clause. The if-clause carries the condition in a simple tense; will/would live in the result clause.
  • If he calls (NOT will call), tell me immediately.
  • If I knew (NOT would know) the answer, I would tell you.

Time runs left to right. Unreal = one step back from its real partner. The number in each circle is the chapter.
Step 4

Hindi Concept Note

अHindi Concept Noteहिंदी में समझिए
Conditional मतलब ‘अगर... तो...’ वाले वाक्य। हर conditional के दो हिस्से हैं: शर्त (if-clause) और नतीजा (result)।
REAL = जो हो सकता है या होता है: अगर बारिश होगी, तो हम नहीं जाएँगे।
If it rains, we will not go.
UNREAL = ख़याली बात: अगर मेरे पास दस करोड़ होते, तो मैं वह plot ख़रीद लेता।
If I had ten crores, I would buy that plot.
ध्यान दें — हिंदी में unreal का signal है ‘होते / होता / लेता’ (…ता form)। English में signal है tense का एक क़दम पीछे जाना: have had, will would।
और सबसे बड़ा rule: हिंदी में ‘अगर बारिश होगी’ future में है, पर English के if-clause में will नहीं आता — If it rains (NOT will rain)।
Step 5

Common Mistakes Hindi Speakers Make

Wrong
Right
Why
If it will rain, we will stay home.
If it rains, we will stay home.
No will in the if-clause. Hindi ‘hogi’ misleads you — English uses present tense there.
If I would have money, I would invest.
If I had money, I would invest.
No would in the if-clause either. The if-clause takes simple past for unreal.
If you heat water it boils.
If you heat water, it boils.
If-clause first comma after it.
We will sign, if the client agrees.
We will sign if the client agrees.
Result clause first no comma.
If prices fell, I will buy.
If prices fell, I would buy. / If prices fall, I will buy.
Don’t mix families: past + would (unreal) or present + will (real). Never past + will.
Suppose if he comes late...
Suppose he comes late... / If he comes late...
‘Suppose’ already means ‘if’ — using both is an Indian-English double.
Step 6

Signal Words

Family-spotting signals:
REAL normal tenses; the speaker believes it can happen
UNREAL tense shifted back (had, knew, were, would have); the speaker is imagining
ifunlessas long asprovided thatin case — all introduce conditions
would / could / might in the result clause = you are in the unreal family
