Dismissed and baffled (7)
I believe the answer is:
stumped
I believe this is a double definition.
'dismissed' is the first definition.
(I've seen this before)
'baffled' is the second definition.
(thesaurus)
'and' is the link.
(Other definitions for stumped that I've seen before include "Perplexed -- way to get out at cricket" , "Baffled" , "in perplexity" , "Dismissed" , "You'd walk if this" .)
