Shared by bee and newt perhaps (7)
I believe the answer is:
between
'shared' is the definition.
Both the answer and definition are adverbs. Maybe there's an association between them I don't understand?
'bee and newt perhaps' is the wordplay.
'and' is a charade indicator (letters next to each other).
'perhaps' indicates an anagram.
'bee' put after 'newt' is 'newtbee'.
'newtbee' with letters rearranged gives 'BETWEEN'.
'by' is the link.
Can you help me to learn more?
(Other definitions for between that I've seen before include "Separating (two things)" , "In the period separating (two events)" , "Amidst" , "In the space dividing" , "Amid" .)
