An experienced martial artist can flay you slowly (9)
I believe the answer is:
andantino
'an experienced' is the definition.
I can't judge whether this definition defines the answer.
'martial artist can flay you slowly' is the wordplay.
I cannot quite understand how this works, but
'can' could be 'tin' (both are metal containers) and 'tin' is located in the answer.
'martial artist' could be 'dan' (dan can mean an advanced level in martial arts) and 'dan' is located in the answer.
The remaining letters 'ano' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for andantino that I've seen before include "at a gentle pace" , "Quite speedy" , "Fairly slow" , "a slowish pace" , "At a light moderate pace (music)" .)
