But we linger outside (7)
I believe the answer is:
however
'but' is the definition.
(I've seen this before)
'we linger outside' is the wordplay.
'linger' becomes 'hover' (synonyms).
'outside' indicates putting letters inside.
'we' placed inside 'hover' is 'HOWEVER'.
(Other definitions for however that I've seen before include "In whatever way" , "Though" , "at all events" , "still" , "at the same time" .)
