Sombre, mournful (8)
I believe the answer is:
funereal
I believe this is a double definition.
'sombre' is the first definition.
(I've seen this before)
'mournful' is the second definition.
(thesaurus)
(Other definitions for funereal that I've seen before include "Of sombre character" , "Gloomy" , "Of the ritual of the dead" .)
