Zero Conditional: certainty


We use the so-called zero conditional when the result of the condition is always true, like a scientific fact.

Take some ice. Put it in a saucepan. Heat the saucepan. What happens? The ice melts (it becomes water). You would be surprised if it did not.

IF

condition

result

 

present simple

present simple

If

you heat ice

it melts.

Notice that we are thinking about a result that is always true for this condition. The result of the condition is an absolute certainty. We are not thinking about the future or the past, or even the present. We are thinking about a simple fact. We use the present simple tense to talk about the condition. We also use the present simple tense to talk about the result. The important thing about the zero conditional is that the condition always has the same result.

*We can also use when instead of if, for example: When I get up late I miss my bus.


IF

condition

result

 

present simple

present simple

If

I miss the 8 o'clock bus

I am late for work.

If

I am late for work

my boss gets angry.

If

people don't eat

they get hungry.

If

you heat ice

does it melt?
