In this lesson, I introduce the concept of conditionals in English and I briefly describe the 4 main types. There are links to detailed lessons for each type of conditional.
Structure of conditionals
A conditional sentence has 2 parts:
- A condition (a situation or circumstance)
- A result or consequence
If the condition is true, then the result will happen.
Example:
If it rains, I will take an umbrella.
The order of words in a conditional sentence is important. We have 2 choices for the form:
Form 1
if + condition + result
We write the condition BEFORE the result. We write a comma (,) after the condition and before the result to represent a slight pause in speech.
Example:
If the shop is open, I will buy a shirt.
Form 2
result + if + condition
We write the condition AFTER the result. There is no comma because there is no pause in the spoken English when we say the sentence.
Example:
I will buy a shirt if the shop is open.
Types of conditionals
There are 4 main types of conditionals in English. They are very briefly defined below along with an example and a link to a detailed lesson for each one.
Zero conditional
Use: to describe facts and things that are always true.
