Like Euler, a notable original! (5,8)
I believe the answer is:
nobel laureate
'like euler a notable original' is the definition.
I can't tell whether this defines the answer.
'euler a notable original' is the wordplay.
'original' is an anagram indicator.
'euler'+'a'+'notable'='euleranotable'
'euleranotable' is an anagram of 'NOBEL LAUREATE'.
Can you help me to learn more?
(Other definitions for nobel laureate that I've seen before include "winner of international repute?" , "International prize-winner" , "Highly honoured person" .)
