What it means
それなのに connects a preceding fact or situation with an unexpected result. It means “and yet” or “despite that,” and emphasizes that the second event contradicts what the first event would normally lead you to expect. It can refer to an entire preceding sentence and is often used at the beginning of a new sentence, although it can also appear within a sentence.
Usage note
それなのに is an independent conjunction, not an inflectional ending attached directly to a noun or verb. Unlike なのに, it normally points back to a previously stated situation and is commonly followed by a comma when it begins a sentence.
