Zero Conditional is one of the four conditional forms in English, alongside First Conditional, Second Conditional, and Third Conditional.

We form it like this:

If (or when) + present simple (condition clause) / present simple (result clause)

The result of the condition is always or usually true if the condition is met. Clauses can be reversed.

It is often written that we use Zero Conditional to talk about FACTS – things which are always true. For example, ‘If you heat water to 100°C, it boils.’

While this is of course true, Zero Conditional is much more widely used than just talking about boiling water! We also use it to talk about the following topics:

INSTRUCTIONS
ABOUT ME
OPINIONS

Here are the four categories with example sentences:

  1. FACTS: If you heat water to 100°C, it boils.
  2. INSTRUCTIONS: If you click here, a new window appears.
  3. ABOUT ME: If I have toothache, I go to the dentist’s.
  4. OPINIONS: If you like jigsaw puzzles, this is one of the best.

Try matching the following sentences to the four categories:

a) If I read without my glasses on, my eyes hurt.

b) If it rains, it’s good for the garden.

c) Plants die if you don’t water them.

d) Ask the teacher if you don’t understand.

e) If I feel ill, I make an appointment with my GP.

q) Pasta tastes awful if you let it boil for too long.

r) If I go to bed late, I feel tired all day.

s) If you need assistance, call this number.
