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' shows that the letters should be reversed in order.
'after' is a charade indicator (letters next to each other).
'holiday' becomes 'trip' (I've seen this in another clue).
'i'+'lo'='ilo'
'ilo' back-to-front is '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" .)
