Maybe 'electric' encapsulates it (3)
I believe the answer is:
eel
'it' is the definition.
The definition suggests a singular noun which matches the answer.
'maybe electric encapsulates' is the wordplay.
'EEL' is hidden within the letters.
However, I am unsure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for eel that I've seen before include "Snake-like sea creature" , "Long smooth fish" , "User of electric organ" , "Proverbially slippery fish" , "Conger, e.g." .)
