Take order from queen, one maid's ordered (9)
I believe the answer is:
randomise
'take order' is the definition.
I know nothing about this answer so I can't tell whether this works.
'queen one maid's ordered' is the wordplay.
'queen' becomes 'r' (abbreviation for regina, e.g. in ER ).
'ordered' indicates an anagram.
'one'+'maids'='onemaids'
'onemaids' with letters rearranged gives 'andomise'.
'r'+'andomise'='RANDOMISE'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for randomise that I've seen before include "Haphazardly set up" , "Dire moans (anag.); make unpredictable" , "Mix up" , "set up unsystematically" , "Scrap order" .)
