CONDITIONAL TYPE ZERO

The "conditional zero" is used when the time referred to is now or always and the situation is real and possible. This type of book is usually used to talk about general facts. The tense of both propositions is the "simple present". In conditional type 0 sentences, the term "if" can usually be replaced by "when" without changing the meaning.

TRAINING

 In the conditional sentences of type 0 ("zero conditional"), the verb tense in both propositions is the "simple present".

Proposición "if" (condición)	Proposición principal (resultado)
"If" + "simple present"	"simple present"
If this thing happens	that thing happens.

As with all conditional sentences, the order of propositions is not fixed. It may be necessary to modify pronouns and punctuation by reversing the order of the propositions but the meaning of the sentence will not change. In "zero conditional" sentences, "if" can be replaced by "when" without affecting the meaning, since both terms serve to express general facts.
