First Conditional Sentences: 50 Example Sentences

Conditional sentences are essential parts of the English language. They help us to talk about possibilities, and plans and even give advice. Among the four types of conditional sentences, the first conditional sentence is the most useful because it describes real and possible situations in the future.

So, what is the first conditional? In short, it’s a way to express what will happen if a certain condition is met. The structure is simple:

👉 If + present simple, will + base verb

For example:

• If you walk every day, you will be fit for a longer time.
• If she makes a new recipe, I will definitely taste it.

See how the if-clause describes a condition and the main clause predicts the result.

You’ll find the first conditional useful when making plans, giving advice, or discussing future possibilities. In this lesson, we’ll explain when and how to use the first conditional and give you 50 examples to practice.

When to Use First Conditional Sentences

Let’s explore some common scenarios where we can use the first conditional sentences:

1. Making Predictions

We can use the first conditional to predict what might happen based on a specific condition. These predictions are logical and likely to occur. For Example:

• If the weather is nice tomorrow, we will go to the beach.
• If you don’t charge your phone, it will run out of battery.

2. Talking About Future Plans or Possibilities

The first conditional is perfect for discussing plans or possibilities that depend on something else happening. For Example:

• If I finish my homework early, I will watch a movie.
• If we save enough money, we will go on a vacation this summer.

3. Giving Warnings or Advice

We can use the first conditional to warn someone about the consequences of their actions or give them advice. For Example:

• If you touch the hot pan, you will burn yourself.
• If you study regularly, you will improve your grades.

4. Explaining Rules or Conditions

We can also use the first conditional to explain rules or what happens under specific conditions. For Example:

• If you don’t wear your uniform, you won’t be allowed into the school.
• If the light turns green, you can cross the street.

Structure of First Conditional Sentences

The first conditional is simple and easy to master once you understand its structure. Let’s break it down step by step!

Basic Structure

👉 If + present simple, will + base verb

• The if-clause describes a condition using the present simple tense.
• The main clause describes the result using will followed by the base form of the verb.

Here are some examples:

• If you study hard, you will pass the test.
• If it rains, we will stay together in our house.

Parts of a First Conditional Sentence

1. The if-clause (Condition):
   • This part explains what needs to happen for the result to occur.
   • Example: If you eat too much,
2. The Main Clause (Result):
   • This part explains what will happen if the condition is met.
   • Example: you will feel sick.

Combined, it becomes:

• If you eat too much, you will feel sick.

Switching the Order

You can switch the order of the if-clause and the main clause without changing the meaning. Just remember to drop the comma when starting with the main clause.

• If you exercise regularly, you will stay healthy.
• You will stay healthy if you exercise regularly.

Both sentences mean the same thing!

Negative First Conditional Sentences

To express a negative condition or result, simply add not in either clause.

• If you don’t sleep well, you will feel tired tomorrow.
• You won’t enjoy the trip if it rains.

Questions in the First Conditional

You can also form questions using the first conditional.

• What will you do if you miss the bus?
• Will she join us if we invite her?
