It might be electric (3)
I believe the answer is:
eel
'it might be electric' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eel that I've seen before include "Electric swimmer, perhaps?" , "Snake-like sea creature" , "Moray or electric, for instance" , "Snaky fish" , "Slender fish" .)
