The scope of the Bard? (7)
I believe the answer is:
breadth
'the scope' is the definition.
(I've seen this in another clue)
'of the bard?' is the wordplay.
'of' indicates an anagram (the answer comes from or 'of' the letters).
'the'+'bard'='thebard'
'thebard' anagrammed gives 'BREADTH'.
(Other definitions for breadth that I've seen before include "Red bath (anag)" , "Wide range" , "Extent from side to side" , "Distance from side to side" , "Liberality" .)
