Chiefs provide parking for home occupants (10)
I believe the answer is:
presidents
'chiefs' is the definition.
(president is a kind of chief)
'parking for home occupants' is the wordplay.
'parking for home' becomes 'p' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'occupants' becomes 'residents' ('resident' can be a synonym of 'occupant').
'p'+'residents'='PRESIDENTS'
'provide' is the link.
Can you help me to learn more?
(Other definitions for presidents that I've seen before include "leaders" , "eg Washington, Adams, Jefferson" .)
