A sign restricting parking repeatedly in Middle East city (6)
I believe the answer is:
aleppo
'middle east city' is the definition.
(I've seen this before)
'a sign restricting parking repeatedly' is the wordplay.
'parking repeatedly' means two substitutions for 'parking'.
'sign' becomes 'leo' (star sign).
'restricting' means one lot of letters goes inside another.
'parking' becomes 'p' (abbreviation on road signs).
'parking' becomes 'p' (abbreviation on road signs).
'p'+'p'='pp'
'leo' enclosing 'pp' is 'leppo'.
'a'+'leppo'='ALEPPO'
'in' is the link.
(Other definitions for aleppo that I've seen before include "War-torn city of Syria" , "Lap Poe around the Syrian city" , "Ancient city, in Syria" , "Largest city in Syria before the massive damage of the civil war" , "Tomorrow" .)
