Fire on combustion ultimately out of control? (7)
I believe the answer is:
inferno
'control?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'fire on combustion ultimately out' is the wordplay.
'ultimately' says to take the final letters.
'out' is an anagram indicator (out can mean wrong or inaccurate).
The final letter of 'combustion' is 'n'.
'fire'+'on'+'n'='fireonn'
'fireonn' is an anagram of 'INFERNO'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for inferno that I've seen before include "hot spot" , "Dante's work" , "Uncontrollable fire" , "Big fire" , "Large and out-of-control fire" .)
