Throw out Yankee dignitary (6)
I believe the answer is:
worthy
'dignitary' is the definition.
(I've seen this before)
'throw out yankee' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'yankee' becomes 'y' (phonetic alphabet: alpha, bravo, charlie etc.).
'throw' with letters rearranged gives 'worth'.
'worth'+'y'='WORTHY'
(Other definitions for worthy that I've seen before include "big cheese?" , "Fit - dignitary" , "Creditable" , "VIP" , "Commendable" .)
