Mastering the conditionals in English is key to communicating real, hypothetical and counterfactual situations accurately. These grammatical structures are common in everyday conversation as well as in academic and work contexts. In this article, you will learn the different types of conditional sentences, how to use them correctly, common mistakes and practical tips for internalising them.
What are conditionals in English?
Conditionals are sentences that express a situation (condition) and its possible outcome. They are usually made up of two parts:
- Conditional clause: Introduced by "if" (if)
- Main clauseExpresses the consequence
These structures allow us to talk about possibilities, future consequences, unreal situations or events that did not happen. For example:
If I see her, I will tell her.
(If I see her, I'll tell her.)
Depending on the context and verb tense, there are several types of conditional structures in English.
Types of conditionals in English
1. Zero Conditional
This type is used for general facts, routines or scientific laws. It is common in instructions and rules.
Structure:
If + present simple, present simple
Examples:
- If you don't water plants, they die.
- If it rains, the ground gets wet.
- If people eat too much sugar, they gain weight.
2. First Conditional
The first type of conditional sentence is used to express real or possible situations in the future. It is based on conditions that can be fulfilled.
Structure:
If + present simple, will + infinitive
Examples:
- If we leave now, we will arrive on time.
- If you study, you will pass the exam.
- If it gets cold, I will wear a jacket.
Council: This type is very useful for making promises, warnings or plans.
3. Second Conditional
It is used to talk about improbable or unrealistic situations in the present or future. The condition is unlikely or purely imaginary.
Structure:
If + past simple, would + infinitive
Examples:
- If I won the lottery, I would travel the world.
- If she were taller, she could be a model.
- If we lived in Paris, we would eat croissants every day.
Note: Although "was" is grammatically correct, "were" is preferred in this type for formal style (If I were...).
4. Third Conditional
This type refers to situations that did not occur in the past and their hypothetical consequences. It is used to express regret, criticism or nostalgia.
Structure:
If + past perfect, would have + participle
Examples:
- If I had studied harder, I would have passed the test.
- If they had left earlier, they wouldn't have missed the flight.
- If we had taken a taxi, we would have arrived on time.
5. Mixed Conditionals
These structures combine different verb tenses to talk about past conditions with consequences in the present or vice versa.
Examples:
- If I had gone to bed earlier, I wouldn't be so tired now.
- If she were more organised, she would have met the deadline.
