Stirs around drink (4)
I believe the answer is:
soda
'drink' is the definition.
(soda is a kind of drink)
'stirs around' is the wordplay.
'stirs' becomes 'ados' ('ado' can be a synonym of 'stir').
'around' says the letters should be written in reverse.
'ados' written backwards gives 'SODA'.
(Other definitions for soda that I've seen before include ""Splashed" drinks mixer" , "Drink containing carbonated water and sometimes flavouring" , "Soft drink" , "Mixer drink" , "Whisky mixer" .)
