It's put about concerning bore (4)
I believe the answer is:
tire
'bore' is the definition.
(I've seen this in another clue)
'it's put about' is the wordplay.
'it' becomes 'e' ('e' can mean 'electronic' which is similar to 'IT').
'put' becomes 'rit' (I can't explain this - if you can you should give a lot more credence to this answer).
'about' is a reversal indicator.
'e'+'rit'='erit'
'erit' back-to-front is 'TIRE'.
'concerning' is the link.
Can you help me to learn more?
(Other definitions for tire that I've seen before include "Weaken" , "Become weary" , "Get weary" , "Flag" , "Feel in need of rest" .)
