Polished, cut by editor then specified another way (9)
I believe the answer is:
redefined
'specified another way' is the definition.
'redefined' can be an answer for 'specified' (redefining is a kind of specifying). I am not certain of the 'another way' bit.
'polished cut by editor' is the wordplay.
'polished' becomes 'refined' (synonyms).
'cut by' is an insertion indicator (some letters cut their way into a word).
'editor' becomes 'ed' (abbreviation).
'refined' going around 'ed' is 'REDEFINED'.
'then' is the link.
Can you help me to learn more?
(Other definitions for redefined that I've seen before include "Again determined" , "specified differently" , "Given a new explanation" .)
