More furious head abandoned area (10)
I believe the answer is:
wilderness
'abandoned area' is the definition.
(I know that wilderness are often abandoned)
'more furious head' is the wordplay.
'more furious' becomes 'wilder' ('wild' can be a synonym of 'furious').
'head' becomes 'ness' (ness is a headland).
'wilder'+'ness'='WILDERNESS'
(Other definitions for wilderness that I've seen before include "Inhospitable region" , "for a time unrecognised" .)
