Solvers are aware of person though I won't name them explicitly (3-4-3)
I believe the answer is:
you-know-who
'person though i won't name them explicitly' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'solvers are aware of' is the wordplay.
I cannot really see how this works, but
'solvers' could be 'you' (the person or people solving the crossword) and 'you' is located in the answer.
'of' could be 'o' and 'o' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for you-know-who that I've seen before include "That familiar person" , "Unspecified but known person" , "Unnamed but well-known person" .)
