White? Not he, the clever fellow! (3)
I believe the answer is:
wit
'clever fellow' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'white? not he' is the wordplay.
'not' suggests deleting specific letters.
'white' with 'he' taken out is 'WIT'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for wit that I've seen before include "Funny person" , "Mental ability" , "Ingenuity or verbal fun" , "Intelligence; humorous person" , "Humour or common sense" .)
