Right work inserted in literary collection for man's study (12)
I believe the answer is:
anthropology
'man's study' is the definition.
(study of humanity)
'right work inserted in literary collection' is the wordplay.
I cannot really understand how this works, but
'right' could be 'r' (abbreviation) and 'r' is found in the answer.
'work' could be 'op' (abbreviation for opus) and 'op' is found within the answer.
'collection' could be 'anthology' (anthology is a kind of collection) and 'anthology' is found within the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'for' acts as a link.
Can you help me to learn more?
(Other definitions for anthropology that I've seen before include "Study of humankind" , "Study of human beings and their way of life" .)
