She will talk about cuts (6)
I believe the answer is:
gashes
'cuts' is the definition.
('gash' can be a synonym of 'cut')
'she will talk' is the wordplay.
I cannot quite see how this works, but
an anagram of 'she' is 'hes' which is present in the answer.
'talk' could be 'gas' (gas can mean to chat) and 'gas' is found within the answer.
No letters remain.
This may be the basis of the 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" .)
