I clear up spilled rum (8)
I believe the answer is:
peculiar
'rum' is the definition.
(synonyms)
'i clear up spilled' is the wordplay.
'spilled' is an anagram indicator.
'i'+'clear'+'up'='iclearup'
'iclearup' anagrammed gives 'PECULIAR'.
(Other definitions for peculiar that I've seen before include "'Strange, odd (8)'" , "Odd, rum, funny" , "Out of the ordinary" , "Belonging exclusively to, person or place" , "Extraordinary" .)
