He gives notice (8)
I believe the answer is:
reviewer
This could be a double definition.
'he' is the first definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'notice' is the second definition.
(thesaurus)
'gives' acts as a link.
Can you help me to learn more?
(Other definitions for reviewer that I've seen before include "Writer who assesses the merits of a book, play etc." , "One should be critical" , "Writer of criticism" , "Writer on films, books, etc" , "critical sort" .)
