She will talk about cuts (6)
I believe the answer is:
gashes
'cuts' is the definition.
(gashing is a kind of cutting)
'she will talk' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'she' is 'hes' which is located in the answer.
'talk' could be 'gas' (I've seen this before) and 'gas' is found within the answer.
No letters remain.
This may be the basis of clue (or it may be nonsense).
'about' is the link.
Can you help me to learn more?
(Other definitions for gashes that I've seen before include "Deep cuts or wounds" , "Deep cuts made with a sharp instrument" , "Makes deep cut or wound" .)
