Listen! An object is connecting to the ground (8)
I believe the answer is:
earthing
'ground' is the definition.
(I know that ground can be written as earthing)
'listen an object is connecting to the' is the wordplay.
I cannot really see how this works, but
'an' could be 'i' (Roman numeral for one) and 'i' is found in the answer.
'object' could be 'earth' (Earth is an example) and 'earth' is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for earthing that I've seen before include "Going to ground" , "Electrician's work" .)
