Go when given licence to acquire northern flavoured sweet (10)
I believe the answer is:
peppermint
'sweet' is the definition.
(peppermint is a kind of sweet)
'go when given licence to acquire northern flavoured' is the wordplay.
I cannot really understand how this works, but
'go' could be 'pep' (I've seen this before) and 'pep' is present in the answer.
'when' could be 'e' (I've seen this in other clues) and 'e' is present in the answer.
'northern' could be 'n' (abbreviation e.g. N. Ireland) and 'n' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for peppermint that I've seen before include "Sweet flavoured with aromatic oil" , "Pungent sweet" , "Aromatic plant" , "flavour" , "herb" .)
