Invitation for Keats: a novel to devour (4,1,4)
I believe the answer is:
take a seat
'invitation' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'keats a novel to devour' is the wordplay.
'novel' is an anagram indicator (letters in a new or novel order).
'to devour' becomes 'eat' (to eat is to devour or consume).
'keats'+'a'='keatsa'
'keatsa' is an anagram of 'takeas'.
'takeas'+'eat'='TAKE A SEAT'
'for' is the link.
Can you help me to learn more?
(Another definition for take a seat that I've seen is " Sit down".)
