Loves to read so badly (6)
I believe the answer is:
adores
'loves' is the definition.
(adoring is a kind of loving)
'read so badly' is the wordplay.
'badly' indicates anagramming the letters (letters in the wrong order).
'read'+'so'='readso'
'readso' with letters rearranged gives 'ADORES'.
'to' acts as a link.
(Other definitions for adores that I've seen before include "is lover" , "Loves; reveres" , "Idolises" , "holds dear" , "Soared (anag.)" .)
