Highly decorated troops rejected non-fighter repeatedly (6)
I believe the answer is:
'highly decorated' is the definition.
The answer and definition are different parts of speech. However, adjectives and past participle verbs occasionally mean the same thing.
'troops rejected non-fighter repeatedly' is the wordplay.
'troops' becomes 'or' (military abbreviation for other ranks).
'rejected' is a reversal indicator.
'non fighter' becomes 'co' (I can't justify this - if you can you should give a lot more credence to this answer).
'repeatedly' shows that letters should be duplicated.
'or' reversed gives 'ro'.
'co' duplicated is 'coco'.
Can you help me to learn more?
(Other definitions for rococo that I've seen before include "Grotesque" , "Ornate late baroque style" , "18th-century French style" , "Ornate style of decoration." , "Fanciful decoration" .)
