Listens during genuine read-through (9)
I believe the answer is:
rehearsal
'read-through' is the definition.
I can't judge whether this definition defines the answer.
'listens during genuine' is the wordplay.
'listens' becomes 'hears' (I've seen this in another clue).
'during' indicates putting letters inside.
'genuine' becomes 'real' (associated in meaning).
'hears' placed into 'real' is 'REHEARSAL'.
Can you help me to learn more?
(Other definitions for rehearsal that I've seen before include "preparation in house?" , "Dramatic practice" , "show trial" , "Practice in theatre etc" , "Drill" .)
