Process of tailoring brightly coloured suit (9)
I believe the answer is:
redaction
'process' is the definition.
(I have seen 'process of censorship' mean 'redaction' so perhaps 'process' could also mean 'redaction')
'coloured suit' is the wordplay.
'coloured' becomes 'red' (similar in meaning).
'suit' becomes 'action' (synonyms).
'red'+'action'='REDACTION'
'of tailoring brightly' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for redaction that I've seen before include "text version" , "process of censorship" , "Amended written account" , "writing" , "Edited version" .)
