Grammar › Conditionals & Wishes › First Conditional

The rule in one sentenceFor a real thing that can happen, use if + present simple for the if-part and will + verb for the result.

About the film

Chicken Little is a film from 2005. Chicken Little is a very small chicken with big glasses. If he says the sky is falling, the town will laugh. If a piece of the sky falls, it will hit him on the head. If the aliens come, his friends Abby, Runt and Fish will help.

What does it do?

You use this pattern for a real thing in the future. It can happen, or maybe not. The sentence has two parts.

The if-part is the thing that can happen. The result is what happens next. The if-part uses the present simple. The result uses will.

If the sky falls, everyone will panic.
If Chicken Little hits the ball, the school will cheer.
If Kirby is lost, the aliens will look for him.

The two parts can change places. With the if-part first, you need a comma. With the result first, you do not.

The if-part
The result
a worry If the sky falls,
everyone will run.
a plan If Buck comes to the game,
Chicken Little will play well.
a promise If you need help,
Abby will be there.
a warning If Runt sees an alien,
he will scream.

People say the short form of will. Learn both:

I will → I’llhe will → he’llshe will → she’llwe will → we’llthey will → they’llwill not → won’tthere is no “will” (and no ’ll) in the if-part

If the town laughs at him, Chicken Little will feel sad. Chicken Little will feel sad if the town laughs at him.
Same idea, two orders. The if-part stays in the present simple. The result keeps “will”.

The if-part is about the future. But the verb stays in the present simple. Do not put “will” after “if”.

If Buck believes his son, Chicken Little will be happy.
Fish will be fine if his helmet stays full of water.
If the aliens find Kirby, they will go home.
The town won’t listen if he shouts again.

How to make it

The result will + verb

person or thing+will+verb
+

If the sky falls, the town will panic.

−

If the sky falls, Buck won’t stay at home.

won’t = will not
?

Will the town believe him if he shows the piece?

Will + person + verb + …

The if-part if + present simple

if+person or thing+present simple
+

If Abby helps, Chicken Little will feel better.

−

If Buck doesn’t listen, his son will be sad.

if + don’t / doesn’t + verb
?

Will his son be sad if Buck doesn’t listen?

In a question, will comes before the subject.

When to use each one

The if-part — the thing that can happen

  • A real chance: If a piece of the sky falls, it will hit someone.
  • A plan: If Chicken Little plays today, Buck will watch.
  • A worry: If the aliens see us, we will run.
  • With not: If Kirby doesn’t come home, his parents will look for him.

The result — what happens next

  • What people do: If the sky falls, the town will panic.
  • A promise: If you need me, I’ll help you.
  • A warning: If Runt sees an alien, he’ll scream.
  • With not: If he shouts again, the town won’t listen.

Words that help: which half?

Some words tell you which half you are in.

The if-part → present simple

The result → will + verb

Common mistakes

❌ If the sky will fall, everyone will panic.

✅ If the sky falls, everyone will panic.

No “will” in the if-part. The if-part uses the present simple.

❌ If Buck believes him, Chicken Little will happy.

✅ If Buck believes him, Chicken Little will be happy.

After “will” you need the verb: will be happy.

❌ If Runt see an alien, he will scream.

✅ If Runt sees an alien, he will scream.

Runt is one person. He / she / it → add -s to the verb.

❌ The aliens will go home, if they find Kirby.

✅ The aliens will go home if they find Kirby.

The comma comes only when the if-part is first.

One more thing

This part is a little harder. You can come back to it later.

Always true, or one time? When a thing is always true, both parts use the present simple. This is the zero conditional. When it is one real time in the future, the result uses will.
✅ If it rains, the ground gets wet. (always)
✅ If Fish loses his helmet, he will need water. (one time, soon)

Practice: choose the right word

Eight questions. Choose one word. You get the answer, and why.

1. If the sky ___, everyone will panic.

No “will” in the if-part → falls.

2. If Runt sees an alien, he ___.

The result needs “will” → will scream.

3. Buck will be proud ___ Chicken Little hits the ball.

The if-part can come second → if.

4. If the aliens ___ Kirby, they will go home.

Present simple after “if” → find.

5. If Abby is there, she ___ help.

The result → will + verb.

6. If Buck ___ listen, his son will be sad.

In the if-part, “not” is don’t / doesn’t → doesn’t.

7. If the town laughs, Chicken Little ___ feel sad.

The result → will feel sad.

8. ___ Fish loses his helmet, he will need water.

The if-part starts with “if”. “Will” goes in the result.

Your turn

Choose one result. Then listen to your sentence.

If the sky falls, …

Chicken Little will be happy if …

Every sentence here is correct. Pick the one you like. Say it out loud too!
