Maybe bow as Roman ordered (7)
I believe the answer is:
oarsman
'maybe bow' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'as roman ordered' is the wordplay.
'ordered' indicates anagramming the letters.
'as'+'roman'='asroman'
'asroman' with letters rearranged gives 'OARSMAN'.
Can you help me to learn more?
(Other definitions for oarsman that I've seen before include "One in an eight?" , "Craft worker" , "It's bordered by Libya and France" , "One in a row" , "A ransom (anag)" .)
