One with electric personality? (4,4)
I believe the answer is:
'electric personality?' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'one with' is the wordplay.
I cannot really understand how this works, but
'one' could be 'i' (Roman numeral) and 'i' is located in the answer.
'with' could be 'w' (abbreviation) and 'w' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for live wire that I've seen before include "Brown covering for this" , "isn't it shocking?" , "Very sparky person" , "'One is very energetic, almost electric (4,4)'" , "Conductor charged with electricity - energetic person" .)
