The electric superstar, least surprisingly - (5)
I believe the answer is:
tesla
'the electric superstar' is the definition.
The definition suggests a singular noun which matches the answer. I also know that 'electric' relates to this answer.
'least surprisingly' is the wordplay.
'surprisingly' indicates anagramming the letters (a surprising ordering of the letters).
'least' is an anagram of 'TESLA'.
Can you help me to learn more?
(Other definitions for tesla that I've seen before include "electrical unit" , "Inventive sort" , "Californian company specialising in electric cars" , "Nikola ---, electricity pioneer" , "Physics unit" .)
