Bond's wound is on head (8)
I believe the answer is:
adhesion
'bond's' is the definition.
('adhesion' can be a synonym of 'bond')
'wound is on head' is the wordplay.
'wound' is an anagram indicator (wound can mean twisted or turned around).
'is'+'on'+'head'='isonhead'
'isonhead' is an anagram of 'ADHESION'.
(Other definitions for adhesion that I've seen before include "Tackiness" , "strong attachment" , "Process of sticking together" , "Stickiness" , "steady attachment" .)
