turn

I'm a little stuck... Click here to teach me more about this clue!

'revolution' is the definition.
(I've seen this before)

'i escaped italian city' is the wordplay.
'escaped' suggests deleting specific letters.
'italian' becomes 'it' (abbreviation for Italian).
'city' becomes 'urn' (I can't justify this - if you can you should give a lot more credence to this answer).
'it' with 'i' taken out is 't'.
't'+'urn'='TURN'

Can you help me to learn more?

(Other definitions for turn that I've seen before include "Rotate - go" , "(Of tide) change from flood to ebb" , "Start" , "Move in a new direction" , "Revolve - go off" .)

I've seen this clue in the Sydney Morning Herald.
