Five vote against getting hold of fresh coal that might explode (7)
I believe the answer is:
volcano
'five vote against getting hold of fresh coal that might explode' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'five vote against getting hold of fresh coal' is the wordplay.
'five' becomes 'V' (Roman numeral).
'vote against' becomes 'no' (I can't explain this - if you can you should believe this answer much more).
'getting hold of' is an insertion indicator.
'fresh' is an anagram indicator (a fresh re-ordering of the letters).
'v'+'no'='vno'
'coal' anagrammed gives 'olca'.
'vno' enclosing 'olca' is 'VOLCANO'.
Can you help me to learn more?
