Saw wound is deep (6)
I believe the answer is:
espied
'saw' is the definition.
(I've seen this in another clue)
'wound is deep' is the wordplay.
'wound' is an anagram indicator (wound can mean twisted or turned around).
'is'+'deep'='isdeep'
'isdeep' anagrammed gives 'ESPIED'.
(Other definitions for espied that I've seen before include "Spotted; saw" , "Caught sight of (poetic)" , "Glimpsed" , "observed in literature" , "Caught sight of (archaic)" .)
