What are conditionals?

Have you ever had issues with conditionals? Are you totally lost when talking about them?
Well, no worries this post will help you to understand conditionals and how to start using them.

There are four types of conditionals.

ZERO
FIRST
SECOND
THIRD
MIXED

Sometimes we call them 'if clauses'. They describe the result of something that might happen (in the present or future) or might have happened but didn't (in the past) . They are made using different English verb tenses.

ZERO CONDITIONAL

We can make a zero conditional sentence with two present simple verbs (one in the 'if clause' and one in the 'main clause'):

• If + present simple, .... present simple.

This conditional is used when the result will always happen. So, if water reaches 100 degrees, it always boils. It's a fact. I'm talking in general, not about one particular situation. The result of the 'if clause' is always the main clause.

The 'if' in this conditional can usually be replaced by 'when' without changing the meaning.

For example: If water reaches 100 degrees, it boils. (It is always true, there can't be a different result sometimes). If I eat peanuts, I am sick. (This is true only for me, maybe, not for everyone, but it's still true that I'm sick every time I eat peanuts)

Here are some more examples:

If people eat too much, they get fat. If you touch a fire, you get burned. People die if they don't eat. You get water if you mix hydrogen and oxygen. Snakes bite if they are scared If babies are hungry, they cry PRACTICE
