Without protection (11)
'without protection' is the definition.
('protection' can be 'defence' (defence is a kind of protection) so maybe 'without protection' can be ''defenceless')
This is all the clue.
(Other definitions for defenceless that I've seen before include "Lacking justification" , "Totally vulnerable" , "Unprotected" , "Without protection" , "Unable to withstand attack" .)
