Medicaster

Medicaster is a noun that refers to a fake doctor. Our word of the day combines the prefix M-E-D-I, which means ‘medical,’ and A-S-T-E-R, which indicates something of inferior or low quality. You could think of medicaster as a synonym for quack. Here’s an example: After spending thousands of dollars on supplements advertised on his show, I concluded that the guy on TV was a medicaster. It became pretty clear that he was a charlatan when my illness didn’t improve after years of gobbling up pills.
