In zero conditional sentences, the if-clause marker is sometimes replaced by the word when.

If is mostly used to express that a situation may happen.

Conditional Clauses—A Reminder

Conditional sentences contain two clauses:

  • Conditional clause (commonly called the if-clause): the condition/situation

  • Main clause: the result

Conditional clause marker: A subordinating conjunction such as the words “if,” “when,” “as,” etc.

 

The if-clause is a dependent clause. To form a complete sentence, it needs the hypothetical result.

Ex:

if-clause

dependent clause

If she cries,

her eyes burn.
