In English, there are complex sentences where one part is a condition (starts with "if") and the second part is the consequence — the result of what happens if the condition works. We call such sentences conditional sentences, or conditionals.
There are 3 types of conditional sentences:
- a real, feasible condition (if you go there, you'll have fun)
- an imaginary condition that refers to the present or to the future (if you went there, you would have fun)
- an imaginary condition that refers to the past (if you had gone there, you would have had fun)
How to make three types of conditionals
||if + present simple
||If you go away, I will miss you.
||if + past simple
||would + infinitive
||If you went away, I would miss you.
||if + past perfect
||would + have + past participle
||If you had gone away, I would have missed you.
