Part of a fast-food combo (4)

Ross

I believe the answer is:

soda

'part of a fast-food combo' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for soda that I've seen before include "kind of water" , "for use with whisky?" , "pressurised liquid" , "Whisky mixer" , "Type of bread, water or fountain" .)

I've seen this clue in the USA Today and The New York Times.
