Still not in Paris, occupying cold Southern French region (8)

'still not in paris occupying cold southern french region' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'still not in paris occupying cold southern french region' is the wordplay.
I cannot really understand how this works, but
'still' could be 'even' (synonyms) and 'even' is found within the answer.
'cold' could be 'c' (eg on taps) and 'c' is present in the answer.
'southern' could be 's' (abbreviation) and 's' is located in the answer.
'region' could be 'e' (E region is an example) and 'e' is present in the answer.
A single letter 'n' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
