Conditional type 0

If/when + simple present

Use: to express a general truth or scientic fact. in this type of conditional, we can use when instead of if.
When the if-clause precedes the main clause, we use a comma to separate the two clauses. For example:

simple present

We use the simple present for:

* facts: the sun rises in the east. it doesn't rise in the west

*consonant: + y + ies / study - he studies

*vowel: + y + - s / play - he plays
