Dripping, a kind of fat (9)
I believe the answer is:
saturated
I believe this is a double definition.
'dripping' is the first definition.
(I've seen this before)
'a kind of fat' is the second definition.
(saturated fat)
(Other definitions for saturated that I've seen before include "Extremely wet" , "Drenched" , "Imbued" , "Thoroughly soaked" , "Such fat as may cause disease" .)
