Totally demolish small Snickers? (9)
I believe the answer is:
slaughter
'totally demolish' is the definition.
I can't tell whether this defines the answer.
'small snickers?' is the wordplay.
I cannot really understand how this works, but
'small' could be 's' (abbreviation - e.g. clothes size) and 's' is present in the answer.
The remaining letters 'laughter' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for slaughter that I've seen before include "best" , "Butchery" , "Mass killing or carnage" , "Glare thus to cause bloodthirsty killing" , "Wholesale killing" .)
