Passages South Carolina censored unthinkingly (10)

'passages' is the definition.
Although both the answer and definition are plural nouns, I cannot see how they can define each other.

'south carolina censored unthinkingly' is the wordplay.
I cannot quite see how this works, but
'south' could be 's' (abbreviation) and 's' is present in the answer.
an anagram of 'censored' is 'recendos' which is located in the remaining letters.
A single letter 'c' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
