Unwisely realigns with US author (8)
I believe the answer is:
salinger
'us author' is the definition.
'salinger' can be an answer for 'author' (JD Salinger). I'm unsure of the 'us' bit.
'unwisely realigns' is the wordplay.
'unwisely' indicates anagramming the letters.
'realigns' with letters rearranged gives 'SALINGER'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for salinger that I've seen before include "'JD..., author of The Catcher in the Rye (8)'" , "US author of The Catcher in the Rye" , "Jerome D ........ wrote ` ` The Catcher in the Rye' '" , "J. D. ..., author of Catcher in the Rye" , "US novelist" .)
