Someone from Dover or Delhi’s attentive picking a news (10)

'someone' is the definition.
(Delawarean is an example)

'dover or delhi's attentive picking a news' is the wordplay.
I cannot really understand how this works, but
'attentive' could be 'aware' (I've seen this before) and 'aware' is found within the answer.
'a' could be 'an' and 'an' is found in the answer.
The remaining letters 'del' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

'from' acts as a link.

Can you help me to learn more?
