Witch in crate moved in old city (8)
I believe the answer is:
carthage
'old city' is the definition.
(I've seen this before)
'witch in crate moved' is the wordplay.
'witch' becomes 'hag' (synonyms).
'in' means one lot of letters goes inside another.
'moved' is an anagram indicator.
'crate' with letters rearranged gives 'carte'.
'hag' placed into 'carte' is 'CARTHAGE'.
'in' is the link.
(Other definitions for carthage that I've seen before include "Hannibal's home city" , "Dido was queen of this ancient city in N Africa" , "Old African city" , "Phoenician city state near modern Tunis" , "Ancient N. African city" .)
