Bit of a near thing in an electrical connection (5)
I believe the answer is:
earth
'electrical connection' is the definition.
(I've seen this before)
'bit of a near thing in' is the wordplay.
'bit of' says the answer is hidden in the clue.
'EARTH' is hidden in the letters of 'near thing in'.
'an' acts as a link.
(Other definitions for earth that I've seen before include "our home" , "cost of which is very high" , "Third rock from the Sun" , "Solid ground" , "Land" .)
