Eg hotel booking giving rise to doubt? (11)
I believe the answer is:
reservation
I believe this is a double definition.
'eg hotel booking' is the first definition.
(making a reservation)
'doubt?' is the second definition.
(to have reservations is to have doubts)
'giving rise to' is the link.
(Other definitions for reservation that I've seen before include "Expression of doubt; table booking" , "Putting aside" , "Booking - qualification" , "Expression of doubt (about a claim)" , "Qualification, proviso" .)
