What's heard from stern-faced story-teller (5)
I believe the answer is:
grimm
'what's heard' is the definition.
I can't tell whether this defines the answer.
'stern-faced story-teller' is the wordplay.
'stern' becomes 'grim' (synonyms).
'faced story teller' becomes 'm' (I can't explain this - if you can you should believe this answer much more).
'grim'+'m'='GRIMM'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for grimm that I've seen before include "The brothers remembered for their fairy stories" , "German folklorist" , "Old yarn collector" , "taletellers" , "Jacob and Wilhelm -, German folklorists" .)
