Possible university for Australian twin (6)
I believe the answer is:
double
'twin' is the definition.
(identical twins are each other's doubles)
'possible university for australian' is the wordplay.
I cannot really understand how this works, but
'university' could be 'ou' and 'ou' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for double that I've seen before include "Spitting image" , "understudy" , "Increase by 100%" , "Bet - twice as much" , "Offence of leaving one's car where it blocks another" .)
