Some say cat gave birth in African port (9)
I believe the answer is:
mogadishu
'birth in african port' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'some say cat' is the wordplay.
I cannot quite understand how this works, but
'some' could be 'a' and 'a' is present in the answer.
'cat' could be 'mog' (informal British term) and 'mog' is found in the answer.
This explanation may well be incorrect...
'gave' acts as a link.
Can you help me to learn more?
(Other definitions for mogadishu that I've seen before include "foreign capital" , "Somali city" , "Capital of Somalia" .)
