5) The difference between “when” and “if” in
conditional sentences:
● “If” → is used for something that, according to the
speaker might happen (he is not sure).
e.g: we
can spend the afternoon on the beach if the weather is fine.
● “When” → is used for something that, according to the
speaker, will happen (he is sure).
e.g: I
will clean up the kitchen right away when I’m back from work
