It might barely be alight (5,5)
I believe the answer is:
naked flame
'alight' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'it might barely be' is the wordplay.
I cannot really see how this works, but
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is found within the answer.
'be' could be 'am' and 'am' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for naked flame that I've seen is " could it have led to hot water?".)
