Harry, fellow Charles admits to? (6)
I believe the answer is:
hector
'harry' is the definition.
(thesaurus)
'fellow charles admits to?' is the wordplay.
'fellow' becomes 'he' ('he' refers to a man).
'charles' becomes 'cr' (I can't explain this - if you can you should give a lot more credence to this answer).
'admits' means one lot of letters goes inside another (to admit is to allow in).
'cr' enclosing 'to' is 'ctor'.
'he'+'ctor'='HECTOR'
Can you help me to learn more?
(Other definitions for hector that I've seen before include "Trojan prince killed by Achilles in siege of Troy" , "Browbeat, bully" , "Trojan hero - bully" , "Bully (someone) verbally" , "King's son" .)
