Play doctor and primarily nurses in the morning (5)
I believe the answer is:
drama
'play' is the definition.
(I know that play can be written as drama)
'doctor and primarily nurses in the morning' is the wordplay.
'doctor' becomes 'Dr' (abbreviation).
'primarily' says to take the initial letters.
'nurses' means one lot of letters goes inside another (nurse can mean to hold onto or harbour).
'in the morning' becomes 'am' (AM on a clock).
The first letter of 'and' is 'a'.
'dr'+'a'='dra'
'dra' going around 'am' is 'DRAMA'.
(Other definitions for drama that I've seen before include "theatre show" , "Exciting series of events" , "Stage play - turmoil" , "theatre studies" , "spectacle of emotion" .)
