Stories in Sun's issue about Poles (5)
I believe the answer is:
yarns
'stories' is the definition.
('yarn' can be a synonym of 'story')
'sun's issue about poles' is the wordplay.
'sun's issue' becomes 'ray' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'about' is a reversal indicator.
'poles' becomes 'NS' (north and south poles).
'ray' written backwards gives 'yar'.
'yar'+'ns'='YARNS'
'in' is the link.
Can you help me to learn more?
(Other definitions for yarns that I've seen before include "Anecdotes" , "rambling stories" , "Stories, threads" , "Tales; threads" , "Threads spun from wool, cotton, etc." .)
