Implicated -- and worried? (9)
I believe the answer is:
concerned
This clue is a double definition.
'implicated' is the first definition.
(thesaurus)
'worried?' is the second definition.
('concern' can be a synonym of 'worry')
'and' acts as a link.
(Other definitions for concerned that I've seen before include "Worried, anxious" , "Feeling or showing worry or solicitude" , "anxiety" , "Involved - worried" .)
