Miss holiday abroad (5,3)
I believe the answer is:
leave out
'miss' is the definition.
('leave out' can be a synonym of 'miss')
'holiday abroad' is the wordplay.
'holiday' becomes 'leave' (I've seen this before**).
'abroad' becomes 'out' (I've seen this before).
'leave'+'out'='LEAVE OUT'
(Other definitions for leave out that I've seen before include "not put away" , "Omit, do not include" , "Drop" , "Omit, overlook" , "Omit or exclude" .)
