Maid moved between (4)
I believe the answer is:
amid
'between' is the definition.
(I've seen this before)
'maid moved' is the wordplay.
'moved' indicates anagramming the letters.
'maid' anagrammed gives 'AMID'.
(Other definitions for amid that I've seen before include "In the middle of" , "Among" , "Surrounded by" , "'See . . . . the winter's snow' (carol)" , "In the thick of" .)
