Peripheral figure revealed by storyteller on podcast (7)
I believe the answer is:
outlier
'storyteller on podcast' is the definition.
I can't judge whether this definition defines the answer.
'peripheral figure revealed by' is the wordplay.
'peripheral figure' becomes 'lier' (I can't explain this - if you can you should believe this answer much more).
'revealed' becomes 'out' (as in news which is out).
'by' means one lot of letters go next to another.
'lier' put after 'out' is 'OUTLIER'.
Can you help me to learn more?
(Other definitions for outlier that I've seen before include "Statistical anomaly" , "One detached from main grouping" , "Isolated data point" , "Remote member of a group" , "isolated example" .)
