After strike, he provides bandage (6)
I believe the answer is:
swathe
'bandage' is the definition.
(I know that swathe is a type of bandage)
'after strike he' is the wordplay.
'after' says to put letters next to each other.
'strike' becomes 'swat' ().
'swat'+'he' is 'SWATHE'.
'provides' acts as a link.
(Other definitions for swathe that I've seen before include "Bandage completely - band of mown grass" , "Broad strip or area of something" , "Wrap in layers of, say, bandages" , "row after reaping" , "Envelop" .)
