Shrewd behaviour from Stallone? (7)
I believe the answer is:
slyness
'shrewd behaviour' is the definition.
'slyness' can be an answer for 'behaviour' (I have seen 'Cunning behaviour ' mean 'slyness' so perhaps 'behaviour' could also mean 'slyness'). I am not certain of the 'shrewd' bit.
'stallone?' is the wordplay.
I cannot quite see how this works, but
'stallone?' could be 'sly' (nickname for Sylvester Stallone) and 'sly' is found within the answer.
The remaining letters 'ness' 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).
'from' acts as a link.
Can you help me to learn more?
(Other definitions for slyness that I've seen before include "Cunning behaviour" , "Cunning; guile" .)
