  • This chapter will discuss the zero conditional in English. This zero conditional is used to talk about general facts, such as scientific events, where the condition and the results always meet. 

    Definition and usage of the zero conditional 

    The conditional zero is used to talk about general facts, to give instructions, and for scientific facts. The zero conditional uses the present simple tense, because it refers to a time that is now or always. The situation is always real and possible. 

    Use Example
    General facts
    • If you don't give your plants enough water, they die.
    • If you drop your phone, it breaks. 
    To give instructions
    • If he phones, tell him I am on my way.
    • If you are not sure what to do, ask your parents for advice. 
    Scientific facts
    • If you heat water, it boils.
    • If you freeze water, it turns into ice. 

    enlightenedThe imperative should be used when giving instructions using the conditional zero. 

    Structure of zero conditional

    The conditional zero tense consists of two clauses, the 'if clause' and the 'main clause'. The structure of the zero conditional begins with the word 'if' followed by a present simpe tense that establishes the condition, which is the 'if clause'. The 'if clause' is followed by the 'main clause' which describes the result in the present simple tense. 

    Structure: If + present simple + present simple.

    If clause (condition) Main clause (result)
    If it rains, the streets get wet.
    If you mix blue and yellow, you get green. 

    enlightenedIn the zero conditional tense the word 'if' can usually be replaced by 'when', without changing the meaning of the sentence.
