Moral tale raised in heel bar, apparently (7)
I believe the answer is:
parable
'moral tale' is the definition.
(I've seen this before)
'raised in heel bar apparently' is the wordplay.
'raised' says the letters should be written backwards.
'in' indicates the answer is hidden within the clue.
'elbarap' is hidden within 'heel bar apparently'.
'elbarap' written backwards gives 'PARABLE'.
(Other definitions for parable that I've seen before include "Short moral story" , "Moral-carrying story" , "Story with ethical point" , "Instructive story" , "Exemplum" .)
