When do verbs end in ar/er/ir instead of are/ere/ire?
I've been studying Italian for a few months, and I've learned that verbs end with are, ere or ire. However, I've started reading some Italian and I've seen many cases where the "e" seems to be dropped. I understand cases such as dargli ribellarsibecause the e is replaced by the direct object. But why is the "e" dropped in cases like Come poter dar torto a ...I would have expected the above to be Come potere dare torto a ...and I would really like to understand the rule for when the following "e" is dropped.
