Sane lawmaker surrounded by crooked economists (6,6)
I believe the answer is:
compos mentis
'sane' is the definition.
(similar in meaning)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for compos mentis that I've seen before include "Of sound mind (Latin)" , "Capable of reasoning" , "Sane" .)
