I'm struggling with oriental heat (10)
I believe the answer is:
eliminator
'heat' is the definition.
(I've seen this before)
'i'm struggling with oriental' is the wordplay.
'struggling with' indicates anagramming the letters.
'im' anagrammed with 'oriental' can make 'ELIMINATOR'.
(Other definitions for eliminator that I've seen before include "Heat" , "Marine toil (anag) - it gets rid of something" , "Hitman" .)
