Sweet Aussie friend circumnavigated lake (7)
I believe the answer is:
cobbler
'sweet aussie' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'friend circumnavigated lake' is the wordplay.
I cannot really see how this works, but
'lake' could be 'l' (geographical abbreviation) and 'l' is present in the answer.
'friend' could be 'cobber' (cobber is a kind of friend) and 'cobber' is found in the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for cobbler that I've seen before include "One might fix heels" , "At last, I set to work" , "Clobber for shoemaker" , "Shoemaker and repairer" , "Shoemaker/repairer" .)
