He’ll give you some good advice (3)
I believe the answer is:
dad
'he'll give you' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'some good advice' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'DAD' is hidden within 'good advice'.
Can you help me to learn more?
(Other definitions for dad that I've seen before include "Popular father - a palindrome" , "Father, in short" , "Papa" , "Pa" , "Popular and informal father" .)
