They like bananas and split peas (4)
I believe the answer is:
apes
'they like bananas' is the definition.
The definition suggests an adverb but the answer is not.
'split peas' is the wordplay.
'split' indicates anagramming the letters (letters split up and reassembled).
'peas' with letters rearranged gives 'APES'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for apes that I've seen before include "Imitates in every aspect" , "Mimics like primates" , "Species of primate" , "Parrots" , "Zoo animals" .)
