Rope male into group (5)
I believe the answer is:
sheet
'rope' is the definition.
(I've seen this before)
'male into group' is the wordplay.
'male' becomes 'he' (**).
'into' indicates putting letters inside.
'group' becomes 'set' (set is a kind of group).
'he' put inside 'set' is 'SHEET'.
(Other definitions for sheet that I've seen before include "Single piece of paper" , "Bedcover" , "* [MATERIAL]" , "Whence to sing hymns?" , "Large piece of fabric" .)
