Turn up with solicitor, disconcerted (3,3)
I believe the answer is:
put out
'disconcerted' is the definition.
(thesaurus)
'turn up with solicitor' is the wordplay.
'turn' says the letters should be written backwards.
'with' means one lot of letters go next to another.
'solicitor' becomes 'tout' (I've seen this before).
'up' backwards is 'pu'.
'pu'+'tout'='PUT-OUT'
(Other definitions for put out that I've seen before include "expelled" , "Offended; expel" , "Broadcast; inconvenienced" , "Extinguished" , "Expel or inconvenience" .)
