Arab limos going around? Sweet (9)
I believe the answer is:
ambrosial
'sweet' is the definition.
(thesaurus)
'arab limos going around?' is the wordplay.
'going around?' indicates anagramming the letters.
'arab'+'limos'='arablimos'
'arablimos' is an anagram of 'AMBROSIAL'.
(Other definitions for ambrosial that I've seen before include "Heavenly" , "Like special food" , "Divine" , "Delightful" , "delicious" .)
