The lady’s following, to return for rest (6)
I believe the answer is:
others
'for rest' is the definition.
(I've seen this before)
'the lady's following to return' is the wordplay.
'the lady's' becomes 'hers' (her refers to a woman).
'following' says to put letters next to each other.
'return' says the letters should be written in reverse.
'to' in reverse letter order is 'ot'.
'hers' after 'ot' is 'OTHERS'.
(Other definitions for others that I've seen before include "He rots (anag.)" , "The rest" , "Not the ones already mentioned" , "Different ones" , "Not these, alternatives" .)
