Surround; envelop (6)
I believe the answer is:
enfold
I believe this is a double definition.
'surround' is the first definition.
(I've seen this in another clue)
'envelop' is the second definition.
(I know that envelop can be written as enfold)
(Other definitions for enfold that I've seen before include "Clasp" , "Surround completely" , "Wrap up" , "Hug" , "Embrace, envelop" .)
