Small can with label stuck round it for sampling (7)
I believe the answer is:
tasting
'sampling' is the definition.
('taste' can be a synonym of 'sample')
'small can with label stuck round it' is the wordplay.
I cannot really understand how this works, but
'small' could be 's' (abbreviation - e.g. clothes size) and 's' is found within the answer.
'can' could be 'tin' (both are metal containers) and 'tin' is found within the answer.
'label' could be 'tag' (synonyms) and 'tag' is located in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
'for' acts as a link.
Can you help me to learn more?
(Other definitions for tasting that I've seen before include "Savouring" , "Sampling (food)" , "event with wine" .)
