Psychologist in hearing, one who keeps records (8)
I believe the answer is:
annalist
This clue could be a double definition.
'psychologist in hearing' is the first definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'one who keeps records' is the second definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
Can you help me to learn more?
(Other definitions for annalist that I've seen before include "Person creating records" , "Historian" , "One making records" , "Narrator" , "she makes record" .)
