Bookworm confused dear queen (6)
I believe the answer is:
reader
'bookworm' is the definition.
(I've seen this in another clue)
'confused dear queen' is the wordplay.
'confused' is an anagram indicator.
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'dear' anagrammed gives 'read'.
'read'+'er'='READER'
(Other definitions for reader that I've seen before include "Proof checker" , "One who studies - or his book" , "University lecturer, the highest rank below a professor" , "Kind of textbook - or its peruser" , "Senior lecturer" .)
