Thrown IDs purser sorted out (9)
I believe the answer is:
surprised
'sorted out' is the definition.
The answer and definition can be both related to thinking as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'thrown ids purser' is the wordplay.
'thrown' indicates anagramming the letters.
'ids'+'purser'='idspurser'
'idspurser' with letters rearranged gives 'SURPRISED'.
Can you help me to learn more?
(Other definitions for surprised that I've seen before include "left open-mouthed" , "Mildly astonished" , "hit for six" , "Lost for words" , "Startled" .)
