Wine overturned in hurly-burly (4)
I believe the answer is:
ruby
'wine' is the definition.
(thesaurus)
'overturned in hurly-burly' is the wordplay.
'overturned' says the letters should be written in reverse.
'in' says the answer is hidden in the clue.
'ybur' is hidden within 'hurly burly'.
'ybur' written backwards gives 'RUBY'.
(Other definitions for ruby that I've seen before include "A red jewel" , "Deep red variety of corundum" , "Gemstone comprising mainly aluminium oxide" , "Completely" , "Deep red - transparent gemstone" .)
