Doctor ran to cure one telling stories (9)
I believe the answer is:
raconteur
'one telling stories' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'doctor ran to cure' is the wordplay.
'doctor' indicates an anagram.
'ran'+'to'+'cure'='rantocure'
'rantocure' with letters rearranged gives 'RACONTEUR'.
Can you help me to learn more?
(Other definitions for raconteur that I've seen before include "One relates" , "Amusing fellow" , "one with a gift for relation" , "After-dinner speaker, maybe" , "One who tells amusing tales" .)
