She treats good person after obsessive year (7)
I believe the answer is:
analyst
'she treats good person after obsessive year' is the definition.
I can't tell whether this definition defines the answer.
'good person after obsessive year' is the wordplay.
'good person' becomes 'st' (saint).
'after' is a charade indicator (letters next to each other).
'obsessive' becomes 'anal' (anal can mean obsessed with order).
'year' becomes 'y'.
'anal'+'y'='analy'
'st' after 'analy' is 'ANALYST'.
Can you help me to learn more?
(Other definitions for analyst that I've seen before include "One examines the elements of something" , "Student of eg systems or psyche" , "Dissector" , "One making detailed examination" , "Practical chemist" .)
