In between, maid breaks down (4)
I believe the answer is:
amid
'in' is the definition.
'between maid breaks down' is the wordplay.
'maid' can be anagrammed to 'AMID'.
But, I am unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for amid that I've seen before include "A dim sort of preposition" , "Maid (anag)" , "In the thick of" , "In the centre of" , "Surrounded by" .)
