One tells stories in Scottish island climbing hill (8)
I believe the answer is:
narrator
'one tells stories' is the definition.
I can't judge whether this definition defines the answer.
'scottish island climbing hill' is the wordplay.
'scottish island' becomes 'arran' (island off the coast of Scotland).
'climbing' shows that the letters should be reversed in order (in a down clue, letters climb up).
'hill' becomes 'tor' (tor is a kind of hill).
'arran' back-to-front is 'narra'.
'narra'+'tor'='NARRATOR'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for narrator that I've seen before include "Storyteller" , "taleteller" , "reporter" , "Anecdotist" , "One who tells the tale" .)
