As I understand:
أنْ (an) is the أَنْ المصدرية and the verb with أَنْ can be replaced by a مصدر.
أَنَ (anna) takes the subject of the coming clause in the accusative immediately after it (you don’t have an option).
But what is إنَّ (inna)? And how do I know whether I should use أنْ, أنَّ or إنَّ?
Do they all mean “that” in English?
