Dormant; passive (6)
I believe the answer is:
torpid
I believe this clue is a double definition.
'dormant' is the first definition.
(I know that dormant can be written as torpid)
'passive' is the second definition.
(thesaurus)
(Other definitions for torpid that I've seen before include "Inert" , "Slow, dull" , "Sluggish and inactive" , "Lethargic - drop it (anag)" , "Physically inactive" .)
