Not written in morality play (4)

I believe the answer is:

oral

'not written' is the definition.
(I've seen this in another clue)

'in morality play' is the wordplay.
'in' indicates a hidden word.
'ORAL' is hidden in the letters of 'morality play'.

(Other definitions for oral that I've seen before include "Concerning the mouth" , "Spoken test" , "By word of mouth (4)" , "See 18" , "Using speech rather than writing" .)

I've seen this clue in The Irish News.
