City I see returning after holiday (7)
I believe the answer is:
tripoli
'city' is the definition.
(Tripoli is an example)
'i see returning after holiday' is the wordplay.
'see' becomes 'lo' (archaic exclamation meaning 'look!').
'returning' is a reversal indicator.
'after' means one lot of letters go next to another.
'holiday' becomes 'trip' (I've seen this before).
'i'+'lo'='ilo'
'ilo' reversed gives 'oli'.
'oli' put after 'trip' is 'TRIPOLI'.
(Other definitions for tripoli that I've seen before include "Lebanese port" , "where there's been regime change" , "Libyan city" , "Port city of Lebanon" , "City in Libya - city in Lebanon" .)
