It brings a guy down to earth (4-3)

I believe the answer is:

tent-peg

'it' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'a guy down to earth' is the wordplay.
'a guy' becomes 'tent' (I've seen this before).
'down to earth' becomes 'peg' (I can't justify this - if you can you should give a lot more credence to this answer).
'tent'+'peg'='TENT-PEG'

'brings' is the link.
