Incident record is of daily events, primarily (7)
I believe the answer is:
'incident' is the definition.
(I've seen this in another clue)
'record is of daily events primarily' is the wordplay.
'record' becomes 'ep' (abbreviation for extended play record).
'primarily' indicates taking the first letters.
The first letters of 'of daily events' is 'ode'.
(Other definitions for episode that I've seen before include "Bout" , "Musical passage" , "Incident in a story or part of a serial" , "Distinctive happening" , "Incident or one part of a story" .)
