Don’t do away with Phoenician city corporation (5,4)
I believe the answer is:
spare tyre
'corporation' is the definition.
(I've seen this before)
'don't do away with phoenician city' is the wordplay.
'don't do away' becomes 'spare' (I am not sure about this - if you are sure you should believe this answer much more).
'with' means one lot of letters go next to another.
'phoenician city' becomes 'tyre' (I've seen this before).
'spare'+'tyre'='SPARE TYRE'
Can you help me to learn more?
(Other definitions for spare tyre that I've seen before include "Car wheel part or inflated tummy" , "Form of extra weight" , "One ought to go on the wagon, just in case" , "large corporation" , "rubber one gaining traction?" .)
