In a story, it's no good to confuse things (6)
I believe the answer is:
tangle
'confuse things' is the definition.
'tangle' can be an answer for 'confuse' (I've seen this before). I'm not certain of the 'things' bit.
'in a story it's no good' is the wordplay.
'in' indicates putting letters inside.
'a story' becomes 'tale' ('tale' can be a synonym of 'story').
'it's no good' becomes 'ng' (abbreviation).
'tale' placed around 'ng' is 'TANGLE'.
'to' is the link.
Can you help me to learn more?
(Other definitions for tangle that I've seen before include "Enmesh, snarl up" , "Snarl or confused mass" , "Twist together into a confusing mass" , "jungle" , "Snarl or embroil" .)
