Drink delicately (3)
I believe the answer is:
sip
'drink delicately' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sip that I've seen before include "Tiny amount of drink" , "Drink slowly" , "Smallest drink" , "Small mouthful of fluid" , "Take a little of a drink" .)
