Can it be used as "What's up"?
What is happening?=Cosa sta succedendo?.....what happens?=cosa succede? is not the same. "cosa sta succedendo?" now, in this moment. "cosa succede?" not in this moment. example "cosa succede domani/stasera/dopo ...ect. ?
That is good to know. So, if I understand correctly, the addition of the conjugation of the infinitive 'stare' can indicate an ongoing action?
Is this sentence wrong ?
Qualcuno sistemarci la bomba!
I wrote "What happens next?" - is it totally wrong or does it make sense giving the right context?
What does it happen?. Can anybody explain to me why it is incorrect?.
There is no 'it' in the original sentence. Also 'what happens?' is what the sentence means in English.
