Blue-pencilled by The Times editor (6)
I believe the answer is:
erased
'blue-pencilled' is the definition.
The answer and definition can be both related to change as well as being past participle verbs.
Maybe they are linked in a way I don't understand?
'by the times editor' is the wordplay.
'by' is a charade indicator (letters next to each other).
'the times' becomes 'eras' (era is a kind of time).
'editor' becomes 'ed'.
'eras' next to 'ed' is 'ERASED'.
Can you help me to learn more?
(Other definitions for erased that I've seen before include "Red sea (anag)" , "Removed by rubbing" , "Rubbed out, expunged" , "removed recording" , "torn off" .)
