Men reversing cherry-hued Sierra and Fiats (6)
I believe the answer is:
orders
'fiats' is the definition.
('order' can be a synonym of 'fiat')
'men reversing cherry-hued sierra' is the wordplay.
'men' becomes 'OR' (military abbreviation for other ranks).
'reversing' shows that the letters should be reversed in order.
'cherry' becomes 'red' (synonyms).
'hued sierra' becomes 's' (phonetic alphabet: alpha, bravo, charlie etc.. I am not sure about the 'hued' bit.).
'red' backwards is 'der'.
'or'+'der'+'s'='ORDERS'
'and' is the link.
Can you help me to learn more?
(Other definitions for orders that I've seen before include "Sends away for" , "books" , "Presumably 26 [TURKEY] will have to have taken these" , "Dictates, decrees" , "Monastic societies" .)
