So article before bishop released without reading (9)
I believe the answer is:
therefore
'so' is the definition.
(I've seen this before)
'article before bishop released without reading' is the wordplay.
I cannot quite see how this works, but
'article' could be 'the' (the definite article in English) and 'the' is found in the answer.
'reading' could be 'r' (one of the traditional three R's of education) and 'r' is present in the answer.
This may be the basis of clue (or it may be nonsense).
(Other definitions for therefore that I've seen before include "Thus" , "Consequently - for that reason" , "In consequence" , "It follows" , "as result" .)
