Erato's lute playing is a feature of Homer's work (5-5)
I believe the answer is:
lotus-eater
'feature of homer's work' is the definition.
The definition suggests a singular noun which matches the answer.
'erato's lute playing' is the wordplay.
'playing' indicates anagramming the letters.
'eratos'+'lute'='eratoslute'
'eratoslute' with letters rearranged gives 'LOTUS-EATER'.
'is a' is the link.
Can you help me to learn more?
(Other definitions for lotus-eater that I've seen before include "One indulging in pleasure and luxury, as described in Homer's Odyssey" , "Indolent person" , "One living indolently - mythical person met by Odysseus in North Africa" , "One given to indulgence in pleasure and luxury" .)
