He's entitled, as his dad was (7)
I believe the answer is:
baronet
'entitled as his dad was' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'he's' is the wordplay.
I cannot really see how this works, but
'he' could be 'baron' and 'baron' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for baronet that I've seen before include "Tone bar (anag.)" , "Bent oar (anag.)" , "Member of the British order of honour" , "Lower noble" , "Lowest hereditary title of honour" .)
