Zero conditional Explained!

In English, we use the zero conditional to talk about things that are always true, such as scientific facts, general truths, or routines. The structure of a zero conditional sentence is fairly straightforward:

  1. The "if" clause and the main clause both use the present simple tense.
  2. The sentence structure is usually "if" + present simple verb, then subject + present simple verb.

It's called the "zero" conditional because it's about things that are always, 100% true. When the condition is met, the result always happens.

Here are three examples in different contexts:

  1. Scientific fact: If you heat water to 100 degrees Celsius, it boils. This is a fact that's always true, no matter what.
  2. Routine or habit: If it rains, I carry an umbrella. This is a personal habit that's always true for the speaker.
  3. General truth: If you don't eat, you get hungry. This is a general truth about how the human body works.

Remember, the zero conditional is used for facts, routines, and general truths that are always the same. If the condition happens, the result is certain.
