Still passionate in chamber? (5)
I believe the answer is:
photo
'still' is the definition.
(I've seen this before)
'passionate in chamber?' is the wordplay.
'passionate' becomes 'hot' (associated in meaning).
'in' means one lot of letters goes inside another.
'chamber?' becomes 'po' (I've seen this in other clues).
'hot' placed inside 'po' is 'PHOTO'.
(Other definitions for photo that I've seen before include "Snap - shot" , "Camera picture" , "Picture, in short" , "Camera image" , "Snap, pic" .)
