I clear up spilt rum (8)
I believe the answer is:
peculiar
'rum' is the definition.
(I know that rum can be written as peculiar)
'i clear up spilt' is the wordplay.
'spilt' indicates an anagram.
'i'+'clear'+'up'='iclearup'
'iclearup' anagrammed gives 'PECULIAR'.
(Other definitions for peculiar that I've seen before include "Strange, I clear up" , "Odd - individual" , "Characteristic" , "Belonging exclusively to, person or place" , "Strange, different from the norm" .)
