Dead hot article on current lover (9)
I believe the answer is:
inanimate
'dead' is the definition.
('inanimate' can be a synonym of 'dead')
'hot article on current lover' is the wordplay.
'hot' becomes 'in' (both can mean fashionable).
'article on current lover' becomes 'animate' (I can't justify this - if you can you should give a lot more credence to this answer).
'in'+'animate'='INANIMATE'
Can you help me to learn more?
(Other definitions for inanimate that I've seen before include "Lacking life" , "Unlikely to move" , "Not living" , "Dull" , "wooden" .)
