First Conditional

​The first conditional is one of four types of hypothetical sentence in English, and it is probably the most commonly used

​The first conditional is used to express the future consequence of a realistic possibility now or in the future. For example,

If I miss the train, I’ll take the next one.

​To make a sentence in the first conditional, we use,

If + present simple, will/won’t + verb.

If I pass this exam, I’ll celebrate.

If I pass this exam, I won’t have to do it again.

Like all conditionals we can also invert this structure:

Will + verb if + present simple.

I’ll celebrate if I pass this exam.

I won’t have to do this exam again if I pass it.

​

​Important: Remember that we can also use the modal verb "might/might not" to describe the consequence in the future.
