Symbol making Mediterranean islander angry (7,5)
I believe the answer is:
maltese cross
'symbol making mediterranean' is the definition.
I can't tell whether this defines the answer.
'islander angry' is the wordplay.
'islander' becomes 'maltese' (I've seen this before).
'angry' becomes 'cross' (cross can mean annoyed or angry).
'maltese'+'cross'='MALTESE CROSS'
Can you help me to learn more?
(Other definitions for maltese cross that I've seen before include "Sir John -, English conductor" , "Eight-pointed figure" , "Emblem worn by Knights Hospitallers" , "Design made by four arrow-shaped arms with their points meeting at the centre" , "symbolic of Crusades" .)
