Astonishing disadvantage discovered in Greek capital (11)

Ross

I believe the answer is:

confounding

'astonishing' is the definition.
(thesaurus)

'disadvantage discovered in greek capital' is the wordplay.
'disadvantage' becomes 'con' (as in pros and cons).
'discovered' becomes 'found' (to discover is to find).
'capital' indicates taking the first letters.
The initial letter of 'greek' is 'g'.
'con'+'found'+'in'+'g'='CONFOUNDING'
