Attention to regular repairs (3)
I believe the answer is:
ear
'attention' is the definition.
(having someone's ear is having their attention)
'regular repairs' is the wordplay.
'regular' indicates alternate letters.
The alternate letters of 'repairs' are 'EAR'.
'to' acts as a link.
(Other definitions for ear that I've seen before include "Part of corn plant" , "Appreciation of sounds" , "Lug (colloq.)" , "Discernment musicians need" , "Head of grain" .)
