Passage taken from Zola is legible (5)
I believe the answer is:
aisle
'passage' is the definition.
(aisle is a kind of passage)
'taken from zola is legible' is the wordplay.
'taken from' indicates the answer is hidden within the clue.
'AISLE' can be found hidden inside 'zola is legible'.
(Other definitions for aisle that I've seen before include "Way between seat blocks" , "Passageway in theatre" , "that would-be bride hopes to make it up!" , "Passageway between seating areas" , "Passage between seating areas" .)
