Remove undesirable elements from United in game fit for distribution (8)
I believe the answer is:
fumigate
'remove undesirable elements from' is the definition.
I can't judge whether this defines the answer.
'united in game fit for distribution' is the wordplay.
'united' becomes 'U' (abbreviation as in Man U for Manchester United).
'in' means one lot of letters goes inside another.
'for distribution' is an anagram indicator (letters distributed elsewhere).
'game'+'fit'='gamefit'
'gamefit' is an anagram of 'fmigate'.
'u' going within 'fmigate' is 'FUMIGATE'.
Can you help me to learn more?
(Other definitions for fumigate that I've seen before include "Disinfect using smoke or gas" , "Treat (pests) with vapour" , "Kill with, eg, smoke" .)
