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 in amongst the letters.
However, I'm not sure 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." .)
