Stop paying attention with changeover on holiday (6,3)
I believe the answer is:
switch off
'stop paying attention' is the definition.
(I've seen this before)
'with changeover on holiday' is the wordplay.
'with' is a charade indicator (letters next to each other).
'changeover' becomes 'switch' (I can't explain this - if you can you should believe this answer much more).
'on holiday' becomes 'off' (I've seen this before).
'switch' next to 'off' is 'SWITCH OFF'.
Can you help me to learn more?
(Other definitions for switch off that I've seen before include "Lose concentration" , "Disconnect power" , "Stop paying attention" .)
