Confound, so a hint's in order (8)

Ross

I believe the answer is:

astonish

'confound' is the definition.
(thesaurus)

'so a hint's in order' is the wordplay.
'in order' indicates anagramming the letters (the letters in a new order).
'so'+'a'+'hints'='soahints'
'soahints' with letters rearranged gives 'ASTONISH'.

(Other definitions for astonish that I've seen before include "Confound" , "Startle" , "Shock with surprise" , "are staggering" , "'knock for six'?" .)

I've seen this clue in The Telegraph.
