Ex-president with First from Oxford and two degrees (5)
I believe the answer is:
obama
'ex-president with first' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'oxford and two degrees' is the wordplay.
'two degrees' can mean two substitutions for 'degree'.
'oxford' becomes 'o' (this could be a standard abbreviation which I don't know about).
'and' means one lot of letters go next to another.
'degree' becomes 'BA' (Bachelor of Arts).
'degree' becomes 'MA' (Master of Arts is a type of degree).
'o'+'ba'+'ma'='OBAMA'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for obama that I've seen before include "President awarded the 2009 Nobel Peace Prize" , "in the White House" , "44th US President" , "Former president" , "US president born in Hawaii" .)
