Perhaps privileged American is drawn to sweet drinks (4)
I believe the answer is:
wasp
'perhaps privileged american' is the definition.
'wasp' can be an answer for 'american' (I have seen 'Influential American' mean 'wasp' so perhaps 'american' could also mean 'wasp'). I'm not sure about the 'perhaps privileged' bit.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for wasp that I've seen before include "spiteful person?" , "Flyer" , "Insect; thin (waist)" , "Insect with a sting in its tail" , "Insect often irritating in summer" .)
