Fury seeing a reader cut short (6)
I believe the answer is:
alecto
'fury' is the definition.
(thesaurus)
'a reader cut short' is the wordplay.
'reader' becomes 'lector' ('lector' can be a synonym of 'reader').
'cut short' means to remove the last letter.
'lector' with its final letter removed is 'lecto'.
'a'+'lecto'='ALECTO'
'seeing' is the link.
(Other definitions for alecto that I've seen before include "Fury (Greek myth)" , "One of the Furies; locate (anag.)" , "Fury exhibited" , "One of classical Furies" , "A fury; locate (anag.)" .)
