The expression “frog in your throat” doesn’t come from sounding like a frog because you have a cold or sore throat.
It originates from an actual Middle Ages medical treatment for a throat infection.
Doctors believed that if a live frog was placed head-first into a patient’s mouth the animal would inhale the cause of the hoarseness into its own body.
Thankfully, the practice is long gone, but the expression lives on.
We say when someone has a raspy voice that he has a “frog in his throat”.
