Duck stayed local around muddy green (5,4)
I believe the answer is:
olive drab
'muddy green' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'duck stayed local around' is the wordplay.
'duck' becomes 'o' (resembles zero - 'duck' in cricket).
'stayed' becomes 'lived' (I can't justify this - if you can you should give a lot more credence to this answer).
'local' becomes 'bar' (local can mean someone's local pub).
'around' says the letters should be written backwards.
'bar' written backwards gives 'rab'.
'o'+'lived'+'rab'='OLIVE-DRAB'
Can you help me to learn more?
(Other definitions for olive drab that I've seen before include "Mil. uniform colour" , "Colour of some military uniforms" , "Greyish" , "Dull colour" , "Military uniform colour" .)
