Wenn + verb = Haben

I’m a bit confused. in the instructions there is this example “Wenn du mehr Zeit hättest, könntest du mitkommen”

but in the card learning it say "Wenn du Zeit hast, ruf mich an.

I understand that I miss something, but can’t put my finger on it. what are the reasoning for they why the verb is used in these two sentences?



Hello @Idan.arbesman, let me see if I can make it a little clearer for you.
Wenn du Zeit hast, ruf mich an. = that is Imperative, not Konjunktiv! Wenn is used as a Zeit word here.
Call me, when you have time!

Wenn du mehr Zeit hättest, koenntest du mitkommen. = that is Konjunktiv I! Wenn is used as a condition word here, like if in English.
If you had more time, you could come with me.


Hi, here some help: Wenn du Zeit hast, ruf mich an (when you have time, call me! = you are expected to have time left to do so, at least more than with the second example, which is conditional II)
Wenn du Zeit hättest,… (if you had time= here you are not likely to have time left to do so) you can as well say: Solltest du Zeit haben, … (Should you have time… ) both last examples are rather improbable, while the first one is likely to happen
