Repairs, on and off, getting attention (3)
I believe the answer is:
ear
'attention' is the definition.
(have the ear of someone is to have their attention)
'repairs on and off' is the wordplay.
'on and off' means one should take alternating letters (letters selected on and off at regular intervals).
The alternate letters of 'repairs' are 'EAR'.
'getting' is the link.
(Other definitions for ear that I've seen before include "Heed" , "Fruiting head of corn" , "Aural organ" , "Van Gogh missing body part" , "Auricle" .)
