In broad terms, we idly shuffled around (6)
I believe the answer is:
widely
'around' is the definition.
Both the definition and answer are adverbs. Perhaps there's a link between them I don't understand?
'in broad terms we idly shuffled' is the wordplay.
'in broad' becomes 'w' (I can't explain this - if you can you should give a lot more credence to this answer).
'terms' indicates one should take the final letters (I've seen 'term of' mean this (term can mean the terminus or ending of the word)).
'shuffled' indicates an anagram.
The final letter of 'we' is 'e'.
'e'+'idly'='eidly'
'eidly' with letters rearranged gives 'idely'.
'w'+'idely'='WIDELY'
Can you help me to learn more?
(Other definitions for widely that I've seen before include "To a great degree" , "over a large area" , "Extensively" , "To a large extent" , "Generally" .)
