Hires permits (4)
I believe the answer is:
lets
This could be a double definition.
'hires' is the first definition.
The definition and answer can be both acts as well as being plural nouns.
Perhaps there's a link between them I don't understand?
'permits' is the second definition.
('let' can be a synonym of 'permit')
Can you help me to learn more?
(Other definitions for lets that I've seen before include "we shall serve them again!" , "Leases" , "Rents out or allows" , "Yes" , "Allows or causes to" .)
