Shrewd as Nancy could be (5)

Ross

I believe the answer is:

canny

'shrewd' is the definition.
(both can mean having good judgement)

'nancy could be' is the wordplay.
'could be' indicates anagramming the letters.
'nancy' anagrammed gives 'CANNY'.

'as' acts as a link.

(Other definitions for canny that I've seen before include "Worldly-wise" , "Shrewd like Scotsman" , "Shrewd, knowing" , "Astute" , "Shrewd, clever" .)
