Story seen in new light when taken the wrong way (4)

I believe the answer is:
yarn
'story' is the definition.
(synonyms)
'new light when taken the wrong way' is the wordplay.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'light when' becomes 'ray' (ray is a kind of light. I am not sure about the 'when' bit.).
'taken the wrong way' says the letters should be written backwards.
'n'+'ray'='nray'
'nray' written backwards gives 'YARN'.
'seen in' is the link.
Can you help me to learn more?
(Other definitions for yarn that I've seen before include "A long tale" , "Long involved story" , "Sailor's tale" , "Not fully credible story" , "Fabricated" .)
