η is eta
retrograde makes it “ate”, a likely word ending; assume this is
over -> on
shortened sugar -> gluc? fruct?
verbal pause is “um” or maybe “uh” or “eh”
cop’s criminal -> ?
abbreviated calendar -> cal
Taking the cryptic-clues at face value, it looks like
A medicine [def. which gives CAL???UM GLUC?ONATE
trading out GLUC for CARB – this is definition by example, but
and seeing the obvious missing CI in calcium, give us:
CALCIUM CARBONATE (A medicine [def. + verbal pause [UM] + shortened sugar [CARB] +
+ retrograde Greek η [ATE<])
Wikipedia tells me a confidential or criminal informant
(CI) is a thing, so that answers that too. Yay,
