Nobel prize winner - second person in France to feature twice (4)
I believe the answer is:
tutu
'feature twice' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'nobel prize winner second person in france' is the wordplay.
'nobel prize winner' becomes 'tu' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'second person in france' becomes 'tu' (second-person pronoun in French).
'tu'+'tu'='TUTU'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for tutu that I've seen before include "8 [BALLET] term" , "Ballet-dancer's skirt" , "A ballerina's short skirt" , "Ballerina's costume" , "Ballet dancer's short skirt" .)
