Rise awkwardly, owing what's left (7)
I believe the answer is:
residue
'what's left' is the definition.
(residue means what's left behind)
'rise awkwardly owing' is the wordplay.
'awkwardly' is an anagram indicator.
'owing' becomes 'due' (similar in meaning).
'rise' is an anagram of 'resi'.
'resi'+'due'='RESIDUE'
(Other definitions for residue that I've seen before include "Remains to be seen" , "balance" , "What's left" , "It remains after other parts have been taken away" , "Whatever is left over" .)
