Host Kent, certain to lose both openers (9)
I believe the answer is:
entertain
'host' is the definition.
(entertain can mean to host guests)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for entertain that I've seen before include "Wine and dine" , "Please < flirt with" , "Create a diversion" , "nurse" , "harbour" .)
