Police force briefly ban Miles' organic processes (10)
I believe the answer is:
metabolism
'police' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'force briefly ban miles' organic processes' is the wordplay.
I cannot quite understand how this works, but
'force' could be 'met' (I've seen this in other clues) and 'met' is present in the answer.
'miles'' could be 'm' (abbreviation) and 'm' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for metabolism that I've seen before include "Vital chemical processes in a living organism - mobile ATMs (anag)" , "it's what keeps him going" .)
