Between maid perhaps (4)
I believe the answer is:
amid
'between' is the definition.
(I've seen this in another clue)
'maid perhaps' is the wordplay.
'perhaps' indicates an anagram.
'maid' with letters rearranged gives 'AMID'.
(Other definitions for amid that I've seen before include "Maid (anag)" , "Within" , "Among" , "'See . . . . the winter's snow' (carol)" , "In the course of" .)
