In the City, unfortunately, half feel the need to get away? (5,4)
I believe the answer is:
itchy feet
'the need to get away?' is the definition.
'in the city unfortunately half feel' is the wordplay.
'in' is an insertion indicator.
'unfortunately' is an anagram indicator.
'half' means to take half the letters.
'the'+'city'='thecity'
'thecity' with letters rearranged gives 'itchyet'.
'feel' cut in half is 'fe'.
'itchyet' going around 'fe' is 'ITCHY FEET'.
(Other definitions for itchy feet that I've seen before include "Strong desire to travel" , "They show a strong urge to travel" , "reason for leaving?" , "Restlessness, a desire to travel - or scratch?" , "Have . . . . . . . . . with restless desire to travel" .)
