Writer of words bitter, wrongly spelled in list (10)
I believe the answer is:
librettist
'writer of words' is the definition.
'librettist' can be an answer for 'writer' (librettist is a kind of writer). I am not certain of the 'of words' bit.
'bitter wrongly spelled in list' is the wordplay.
I cannot really see how this works, but
an anagram of 'bitter' is 'ibrett' which is located in the answer.
The remaining letters 'list' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for librettist that I've seen before include "Provider of opera's words" , "Deviser of book" .)
