Great writer, but he makes me snore (7)
I believe the answer is:
emerson
'great writer but he' is the definition.
The definition suggests a singular noun which matches the answer.
'makes me snore' is the wordplay.
'makes' indicates anagramming the letters.
'me'+'snore'='mesnore'
'mesnore' is an anagram of 'EMERSON'.
Can you help me to learn more?
